MacroPad

Just some minor cleanup and finalization of the project, its description, and its GitHub page.

I switched the main MCU from a nRF52840 to the RP2040 for now as I needed to make the board smaller and I would not be able to access the small pads underneath the Xiao nRF52840 with the new design. I also started working more on CAD. Both parts on now complete and I am just finishing up on the firmware.

The initial schematic and PCB routing are done for the Hackpad. I decided to try and make it wireless to add some complexity to the project, so I am using a Xiao nRF52840 instead. I also added hotswap sockets instead of the solder sockets so I could test different switches. I also went with two encoders for more inputs. The setup should also work with the default RP2040; however, the left encoder will not work. Next up is designing the case for it.
