Cardputer adv support

[TheOddCell]

just the keyboard doesn't work but that's pretty major

Thanks for creating an issue for this! I don't have a Cardputer Adv and cant afford to buy one at the moment, so I can't add that support right now. However, if anyone else would like to add support for the Adv as a new Device, I'd be happy to assist!

Otherwise, I might eventually buy one for myself and add the support then :)

As far as I can tell so far:

1. New keyboard wiring so you just can't interact with it (and therefore can't test if the following are true)
2. Apparently there is a new audio processor, IDK if anything needs to be changed for this (also, there's an audio jack but you shouldn't need to change anything should just be handled by the processor)
3. IMU, which doesn't break anything, but should be added to make sure apps can easly use it
4. new GPIO which should just be handled by micropython itself
