SC75823: mapping the H-Buster HBD-2300MP display

SC75823 reconstructs Arduino control of the H-Buster HBD-2300MP front-panel display. It maps 156 individually addressable display bits to segments and symbols, and documents routines for seven-segment digits, fourteen-segment text and display-state updates.
