usb-flasher: Update stock firmware's USB product ID

firmware, and advertised a different product ID.

common: Improve crc8 generation
...
Start with 0xff instead of 0x00, so the CRC will be nonzero (and length
dependent) for data that is all zeroes.
Remove unnecessary masking, since `crc` is already an 8-bit integer.

firmware: Implement scanning block

This allows to disable the keyboard. The firmware will never scan
for keys pressed in this mode, and it will powerdown the MCU most of the
time.

Increase the default flashing area size to 0x2000
...
This does two things:
- more reasonable default because stock firmware size is larger than
the previous default
- it will overwrite 0x3fff with 0xff, so that after flashing stock
firmware the user firmware is automatically disabled

Implement flashing over I2C and user/stock firmware support
...
I2C register layout changed a bit to make various operations easier
to implement in FW and for the user.
Flashing/debugging tools now share more code. Firmware is now more
configurable (it's now possible to compile-out various features).
Self-testing for column-shorts is implemented.
Firmware is optimized for low power consumption.
