CCExtractor version: this would affect versions after 0.88

Necessary information

Is this a regression (i.e. did it work before)? NO
What platform did you use? Windows
What were the used arguments? --norollup

Basically the title.

Simple (?): Look for signs the speaker has changed; like ">" or ">>>" or "Narrator:" or "Oprah:" any of which preceded by a new line, and start the next caption there.

Less Simple: Check if the captions are probably synchronized, and if so, also start a caption after a long pause at the end of a sentence. (Maybe detect uneven timing of characters, as if typed by a stenographer to distinguish live captioning from scripted. Scripted roll-up captions have accurate timing and are sometimes used in news magazine programs and weekly documentary series like Frontline.)

Thanks again, everyone, for all your hard work.

@cfsmp3 commented on GitHub (Mar 2, 2020):

That's probably best done by a post-processing program to be honest. There's no need to add those kind of features directly into the main program.

After all, C is not really a convenient language for string manipulation.

However in Python that would take just a few lines of code.

Closing because: won't-fix (just feel like CCExtractor itself is not the right place).
