Add FN-based mouse mode switch
...
When FN is held:
- Remap buttons to back/forward buttons
- Remap Y-axis as scroll and X-axis as pan

Always tickle watchdog in main loop
...
Otherwise during initial setup or wakeup, nothing may happen for long
enough to trigger a watchdog reset into the bootloader.

These are read on startup to set defaults for:
- debug UART (now defaults to disabled)
- FN/CTRL swap
- FN key row lock (FnLk)

Check for slave clock stretching
...
This indeed fixes the values read back:
80000000ff No buttons, no movement
80010000ff Left button
80050000ff Left+right buttons
80070000ff All buttons
800012fdff Force applied
80000fffff force applied

Add basic I2C support
...
Doesn't quite work yet, most likely the trackpoint interface is using
clock stretching.
Initial values read:
ff 01 ff fd ff
Later values read:
ff 80 ff e0 3f (no buttons pressed)
ff 80 ff e0 7f (left button pressed)
ff 80 ff e0 bf (right button pressed)

Adds support for:
- CLEAR/SET FEATURE (ignored)
- GET_CONFIGURATION (always returns 1 since there is only a single config)
- GET_INTERFACE (always returns 0 since there are not altsettings)

HID keyboard basics working
...
Matrix is getting scanned and converted into boot-style HID interface.
Most keys are basically working.
However the enabled debug UART prevents use of the following keys:
DELETE PRINTSCREEN INSERT PAGEUP PAGEDOWN
as S15 is in fixed output mode and thus can't be sensed right now.

not yet implement any keyboard scanning logic.

Initial version
...
Tested:
- UART debug output works at 115200 baud (pad S15)
- Jumps to bootloader on watchdog timeout
- Jumps to bootloader when Return is held while plugging in USB
- Jumps to bootloader when UTX/URX lines are shorted
- Measured max GPIO toggling speed is 3MHz
