Prior to this change, the UI thread was consuming approx. 10-14% CPU
in the idle state, and appeared to be running in an endless loop.
After this change, the UI thread is measured at about 0.1% CPU. I'm
not sure what the current consumption impact is, but it's gotta be
a power saving, even if slim?
Following manual testing with the device after flashing this change,
the UI responsiveness and music playback does not appear to be
negatively affected. The UI actions that were tested were:
- Scrolling through items on the root menu
- Scrolling through settings
- Scrolling through All Tracks with long-press on the bottom of
the scroll wheel (Page Down) on a device with ~20k songs
- Repeatedly hitting 'next track'
- Forcing a DB update, and scrolling through All Tracks while
updating the database.
The device was configured with the following settings when tested:
- TTS enabled
- Wired headphones
- Bluetooth enabled but not connected
- No DB auto-update
- Playing music

This change introduces the ability to enable or disable the spoken interface/TTS from the on-device settings, either via the UI or the Lua console. This closes out the implementation of issue #245.
The TTS setting is only visible in Display settings if voice samples are present in `/.tangara-tts/` on the SD card.
Playback of new TTS voice samples is inhibited when TTS is disabled. By default, the setting is enabled, as the device will only play back TTS voices if samples are present on disk.
If you need samples to test TTS on your device, feel free to grab the voice samples I have at https://codeberg.org/tursiae/tangara-tts-samples. There's about 80-85% coverage of the UI, with the remainder to be added soonish.

Reported in issue #258.
As of v1.2.0, if /.tangara-tts/ samples are present on the SD card, and
>= 4 menu items with matching TTS samples are highlighted in the UI, and
no audio output (headphones or BT sink) is connected, the `tts::Player`'s
invocation of lambdas on the WorkerPool will result in worker task
exhaustion.
This is because we get stuck in state where the `drivers::PcmBuffer` is
not accepting any new samples, and the inner loop in `Player::decodeToSink`
that pushes to the output isn't checking to see whether playback was
cancelled. So the loop never terminates, and we consume that worker slot.
Repeat with another 3 menu items, and, hey, all four worker threads are
consumed with TTS that will not terminate until headphones/BT are connected.
When `CONFIG_FREERTOS_GENERATE_RUN_TIME_STATS` is not set, the FreeRTOS
scheduler will not keep track of task runtime statistics, and the `tasks`
command on the console will show `nan%` for the usage.
This adds a recommendation for the user to enable the `...STATS` config in
their build, and also updates the guidance for `configUSE_TRACE_FACILITY`
to point at the supported `sdkconfig.local` configuration pathway, instead
of pointing at the `#define` that's deeper in the configuration stack.
Also, the sampling period is dropped from 2.5s to 10ms when the runtime
stats are not enabled; given that we're not measuring any usage, it's not worth
sleeping any longer than that. We might even be able to drop to zero?
`std::sort` expects a comparator that returns `a < b`. Flipping this to `a >= b`
would normally be fine to reverse the order, but floats behave weirdly with NaN.
Instead of flipping the comparator, this uses the reverse-iterators to reverse
the sort order of the tasks, and returns to an `a < b` comparator.
This adds a way for feedback devices to respond to events from outside of LVGL's event system, being passed from input device to feedback device through a vector. This was done so that touch events and long-press triggers can now give feedback through haptics.
This PR also adds haptic modes, saved in nvs similarly to input and locked input modes, to disable or change the haptic effect behaviour based on which mode is selected.
Finally, this also fixes a bug in which some click events would not trigger haptics, at the expense of re-introducing the (undesired?) behaviour of clicking a button that transitions to a new screen causing a double click.
Relevant issues this should close: #195, #233, and (partially?) #120

It turns out that our error prone method of managing nvs keys has led to
an error!
We took a look over the other keys here and it didn't look like any
others were missing.
Fixes#204
- The tag parser's cache is now cleared between indexing runs, preventing stale data from being used
- Multi-value tag fields (genres, all artists) are now properly ingested in the tag value cache
- Cleaning up removed index records now properly handles the case where only a subset of the records for multi-value tags need to be deleted.
- Synthesizing missing tag values is now done in the tag parser instead of TrackTags, which resolves some issues with multi-value tag callbacks from libtags not being handled properly
These fixes seem to address all the issues with stale index records we were able to repro (including the issues in https://codeberg.org/cool-tech-zone/tangara-fw/issues/191), but if you've got any more cases with consistent repros then lmk!

Overflow menu for the now playing screen. New home for the info screen here. Adds quick navigation to current album or artist (thanks tjk!) and clear queue button.
Also fixed up the way the now playing screen looks when queue is cleared (remove previous duration and don't show "loading" if nothing is actively loading).

Queue now has a separate 'ready' property to indicate it's ready to be used, which is independent from whether it's still loading tracks in. This also improves the response time for shuffling all tracks (we will initially pick a random track in the first 100 tracks whilst the rest of the tracks are loading). This should also fix issues where one song will start playing and then repeat itself when the queue finishes loading, and hopefully solve #160 as well (though I couldn't actually repro this myself).
