SRT timestamp parsing: surrounding whitespace · case 02

Every cue from a CRLF subtitle file fails to parse because its end timestamp carries a carriage return.

Case contract

Parse an SRT timestamp HH:MM:SS,mmm to integer milliseconds. Hours have 2 or more digits, minutes and seconds are below 60, the fraction has 1 to 3 digits and is right-padded (",5" means 500 ms), "." is accepted as the separator, surrounding whitespace (including a CR from CRLF files) is ignored; invalid text returns None.

Why this case matters

Subtitle timing defects shift, hide or overlap captions that viewers depend on for comprehension and accessibility.
