flip bot assy drawing

- open/read files _and_ --tty
- more precision for clock fit parameters
- s/data[c]/Data[c]/
- clear old ADC_mV{} results.
  In case of noise, invalid entries may stay around and cause spurious
  warnings
- when reparsing files, prune original lines for checksumming
- when reparsing, silently drop parser output
