Subject: merging gchart's changes, part 1... + added Sofirn LT1S Pro + added
 Sofirn SC21 Pro + added Wurkkos TS10 + added Wurkkos TS25 * small changes to
 other models * improved dual voltage support + added attiny1616 flashing
 python script w/ pymcuprog

These changes are incomplete.  It does not yet include:
- extended simple UI
- t1616 WDT reset detection
- gchart's OUTPUT_MUX code (I plan to rewrite the entire tint system)
