This is version 2.0 pre-release running all devices in report mode and compiled with Pico-SDK 2.1.0.
This should fix #35, #50, #59 and #61, please test multiple different mice.
Also #40 became active again since all devices now run in report mode and NKRO is not finished.

This is another version 1.3 pre-release running all devices in report mode and compiled with Pico-SDK 1.5.1.
I discovered an issue with Pico-SDK 2.0 which I've not analyzed yet.
This should fix #35, #50, #59 and #61, please test multiple different mice.
Also #40 became active again since all devices now run in report mode but NKRO is not finished yet.

Thanks to @seritools for debugging the AMI keyboard controller on 386 boards.

This fixes two bugs regarding ghost mouse movement and key presses mentioned here: #19

Still need to implement the mouse decoupling mentioned here: #1 (comment)

Please note that the keyboard and mouse clock/data lines have to be swapped from now on.

HV1 is now keyboard data
HV2 is now keyboard clock
HV3 is now mouse data
HV4 is now mouse clock

Thanks @serisman

Mouse wheel is now working, code still needs massive cleanup!
