Add i2c display support. This will allow the user to:

  • track device connection status
  • see operation status
  • debug/diagnose without serial at a glance
  • access config menu (when added)

Current target is 128x64 SSD1306 display. Initial tests with some library code have proved unreliable, as the font was small but switching to a larger font caused rendering issues. Suggest porting the code from flashfloppy's stm32 target to the rp2040 i2c layer.
