Other Changes
=============
- Split the bar into negativ [10:5] and positive [5:0] scale and update
  them seperate to have a better visualization.
- Blink red with backside LEDs on detected pulse.
- Allow toggling the LED modes on and off (see new button layout).
- Lock mode & bias during logging.

This patch makes the BHI160 app more pythonic and fixes a few
bugs/issues:

- An exception (including KeyboardInterrupt) will trigger the sensor to
  be closed again.  Otherwise you'd get strange behavior trying to
  reopen then afterwards.
- Use simple_menu.button_events() instead of home-cooked solution.  This
  should hopefully make the code more future-proof.
- Fix overlapping text caused by the font-rendering changes.

As discussed in card10/firmware!316, this commit prevents I2C lockup by
discarding overflowing samples instead of blocking until they have been
read.  This is not ideal as the samples read will not be the most recent
ones.  A deeper refactor of the sensor-stream internal API can fix this
in the future.

756c13df epicardium/rtc: fix numerically unstable subsecond decoding

         the subsecond encoding function from epic_rtc_set_milliseconds
         and the corresponding decoding function from
         epic_rtc_get_milliseconds are not numerically stable.

         i.e., encoding 5 milliseconds to 20 subsecs and immediately
         afterwards decoding that yields 4 milliseconds.

         Adding a bias of 999 (0.24 milliseconds) to the decoding
         function makes it numerically stable, while never decoding any
         subsecond value to more than 999 milliseconds.

There are several common CRC implementations for Python with the currently
used one (crc16) not being available in e.g. Debian.

crcmod and/or crcelk are readily available on several distributions.

Add serial_flush function

Closes #164

See merge request card10/firmware!314

serial_flush() allows flushing the serial buffer from anywhere in
Epicardium.

- When run from thread mode it will flush to UART, CDC-ACM and BLE.
  This is similar to what the serial task would do once it is
  rescheduled.
- When run inside an exception handler, it will only flush to UART
  because CDC-ACM and BLE cannot be flushed from an ISR.  Note that
  characters flushed this way will never appear on the other outputs,
  even if the serial task is scheduled at some point afterwards.

The main use of this function is to ensure output of messages even in
cases of critical failures.
