* Add an ez_maker directpins for rp2040
This allows all exposed pins on the Raspberry Pi Pico to be used
as up to 26 individual keys. Keys use a common ground arrangement.
The firmware is also expected to work on generic RP2040 boards, check
manufacturer pinout diagrams or use trial and error to find out the GP#s
of the pins.
