Implements logic to automatically offset daylight saving time settings
when calculating timezone offsets. This should make the DST functions
work automatically with no need for user input in most cases.

According to the data sheet, writing to a Control A register's ENABLE
bit will trigger write synchronization and set SYNCBUSY's ENABLE bit
which will be automatically cleared by the hardware once the write
operation is complete.
It is necessary to wait until SYNCBUSY's ENABLE bit is clear.
Reading synchronized registers before that returns previous values.
Writing synchronized registers before that drops the write and generates
an error value in another register.
The data sheet recommends polling the ENABLE bit in this situation.

This makes it possible to do a bunch of things without
having to keep touching the light button.
I don't really see any downside with this. If you want
the light to go off, just stop touching buttons.
* Sensor Watch Pro board definition
* Disable hot-plugging on SWCLK
* Add rainbow test
* Move interrupt mapping to board config
* New color definition for Pro boards in makefile
This makes movement_play_signal synchronous when in LE mode, despite
using the underlying asynchronous API. It's a bit of a hack, but it
should work well enough for now.
This also moves the enabling/disabling of the buzzer into the
movement_play_signal function, so that watch faces no longer have to do
it.
* Introduce shell module for basic serial shell with argument parsing
* Introduce shell_cmd_list module for basic compile-time command
registration
* Harden USB handling to hang less and drop fewer inputs
- Service tud_task() with periodic TC0 timer interrupt
- Service cdc_task() with periodic TC1 timer interrupt
- Handle shell servicing in main app loop
- Add a circular buffering layer for reads/writes
* Change newline prints to also send carriage return
* Refactor filesystem commands for shell subsystem
* Introduce new shell commands:
- 'help' command
- 'flash' command to reset into bootloader
- 'stress' command to stress CDC writes
Testing:
* Shell validated on Sensor Watch Blue w/ Linux host
* Shell validated in emscripten emulator
* Tuned by spamming inputs during `stress` cmd until stack didn't crash
These keys are the shortcuts to "press" the alarm, light and mode
buttons. However, they prevent these letters from being input in the
debug console to send filesystem commands. Strangely, there was already
some code to allow typing these letters in the console output, but not
in the input.
When using the simulator, I encountered cases where the light would become stuck on, and the watch
would be unresponsive. In particular, this would occur when pressing the light button on the
sunrise sunset watch face.
I appears that this is caused by a divergence in out the callback mask is interpreted by the
hardware interface, and in the simulator in the following function.
void watch_rtc_disable_matching_periodic_callbacks(uint8_t mask)
In particular, a mask of 0xFE is intended to disable all except the 128hz callback at index 0,
but instead disables all except the 1hz callback at index 7 in the simulator.
