Use , character instead of . for SRT output. (#197)

Browse Source 
The SRT format uses the decimal comma character as the fractional separator rather than the decimal point character. Adjust format_timestamp and write_srt to specify the separator character.

See https://en.wikipedia.org/wiki/SubRip#:~:text=the%20fractional%20separator%20used%20is%20the%20comma%2C%20since%20the%20program%20was%20written%20in%20france.
