Made power traces thicker(0.4mm and 0.3mm). Added GND vias b/w traces

Final CDR Commit

Merge branch 'Rich_Changes_06242022' into 'master'

Most of the board is done. Just need to change the layer of the signal lines.

Added power planes. I may go back and change the stack up as well as the layout for the level shifters.
