[csv] Friendlier defaults for missing cToneFreq/rToneFreq columns in csv import - Fixes #1577

Add a _clean_tmode() function to the generic CSVRadio class in generic_csv.py.
Check for the existence of csv headings "rToneFreq" and "cToneFreq" in the
header line. If exactly one is present, use the value in that column
for both rTone and cTone for each channel imported.
