Adds Configurator support for the Sol rev. 1 by RGBKB.
Notes:
The Sol keyboard supports split thumb keys like the Ergodox - any of the 2u thumb keys can be split into two 1u keys. The matrix here is configured for fully 1u keys on the thumbs.
The Sol also supports installing a rotary encoder on each half. The key matrix given includes the encoders' functions, which are shown in the Configurator as two 1u keys side by side below each half's main key block. The left key of the two (for each side) represents that half's rotary encoder's counter-clockwise function, and the right key is that encoder's clockwise function.
