KMK running on the ESP32-S2

I soldered some pin headers on a PB-Gherkin so that I could connect it to a ESP32-S2 SAOLA-WROVER dev board. These boards are cheap at $8 from Amazon or Digikey. The only real downside is the physical size and the USB HID requires a separate USB pigtail. The micro USB connector on the board is only for serial, useful for the initial flashing of CircuitPython, but not much else.

I modified the config file for the PCA10059. I had to change the pin definitions for the new board. I also commented out the section that rearranges the switches, this PCB is not flipped upside-down.
