Mechanical switches exhibit temporary voltage fluctuations
when electrical contact is made, which manifest as "bouncing"
between the logical high and low states. Sampling the switch's
state during this period of stability produces invalid results.
The switch must be debounced by ignoring the generated interrupts
until the switch's state has stabilized. This is implemented by delaying
the input events until an empirically determined time has elapsed.
As such this pull request introduces customizable high resolution timers
for debouncing button down and up events.
This software debouncing unfortunately increases the sensor watch's
input latency. This is an acceptable tradeoff due to better usability:
watch faces which require holding down buttons such as the pulsometer
should work much more reliably after this patch.

* buzzer sequences: first draft, does not work on hardware yet (but in simulator)
* buzzer sequences: add changes to movement.c
* buzzer sequences: add demo face to Makefile
* buzzer sequences: fix problem of interrupted sounds. Add logic for repeating sub sequences. Tidy up (move logic to watch_buzzer files, remove buzzer_demo_face)
* buzzer sequences: tidy up even more
* buzzer sequences: disable registering a 32 Hz tick callback for watch faces, so it will be used exclusively by the buzzer sequences functionality
* buzzer sequences: add callback slot functionality to watch_rtc and make watch_buzzer use it. Switch internal buzzer sequences tick frequency to 64 Hz. Revert changes to movement.c
* buzzer sequences: fix parameter sanity check in watch_rtc code
* stock stopwatch: first fully functional implementation
* stock stopwatch: fix typo in comment
* stock stopwatch: handle resuming from deep sleep mode properly
* buzzer sequences/watch_rtc: optimize calling tick callbacks in RTC_Handler
* buzzer sequences/watch_rtc: fix error in calling callback functions
* stock stopwatch: implement workaround for sleep mode
* stock stopwatch: merge current main into stock-stopwatch
* stock stopwatch: use TC counters as source for callbacks
* stock-stopwatch: revert unnecessary changes to watch_buzzer

* Add movement_play_alarm_beeps() to movement.c and make alarm sounds customizable. Add alarm indicator to simple watch face.
* Add alarm face
* alarm_face: fix problem with disabling alarms for 00:00.
* Fix typos in comments and get rid of of unused variable warning
* remove unnecessary constant
* simple_clock_face: fix disappearing chime indicator after face switch, enable alarm indicator updates in app loop (for one-time alarms).
movement: handle situations where watch is in sleep mode and chimes fire off at the same time as alarms properly.
* alarm_face: tweak process of displaying things on the lcd. Add extra long and extra short alarms. Increase number of alarm slots to 16.
* alarm face: fix alarms playing one beeping round more than set.
* alarm face: add proper quick cycling of hour and minute setting
* alarm-face: correct am/pm indication and some minor tweaks. Reset movement_config.h to current main branch. simple-watch-face: Remove unnecessary check and swap indicators (alarm / hourly chime)
* alarm-face: reverse commit parts from another branch (accidentially commited logic depending on movement firmware auto firing the long press event)
