Both D0 and D1 were assigned to pin_GPIO7, fixed D0 to pin_GPIO6, which also matches the comment.
I missed a few pin definitions. Fixed those.
Added board definition for the Sparkfun MicroMod RP2040. Mostly followed the format for pins from the MicroMod nRF52840 board definition, as MicroMod tries to standardize pins across microcontrollers.
