- Updated port switching pins (split USB and UART switching)
- Added basic support for 2nd i2c bus
- Updated key matrix
- Fixed udev rules
- Added missing register defines

- Each scan module now has a current change callback which passes the available current as a parameter
- No longer attempts to use the max 500 mA immediately, starts with 100 mA then goes to 500 mA after enumeration
- If enumeration fails due to bMaxPower of 500 mA, then attempt again at 100 mA (might also be possible to go even lower to 20 mA in certain cases)
- Now working with the Apple Ipad (no over-power messages)
- Fixed Wake-up behaviour on Apple Ipad (and likely other iOS devices)
- More effecient set_feature/clear_feature handling (device handler)
- Initial power handling via Interconnect (still needs work to get it more dynamic)

- Works the same as the bootloader variant, waits 1000 ms before attempting to swap
  Only swaps if USB not already intialized
  If USB never initializes, will swap forever

TODO
- Stop swapping if UARTConnect detected and initialized
