Feature Request: Some indicator that generate_timecodes is working

[eaglexboy]

It would be nice if there was some indicator that the ffmpeg subprocess was working (maybe a tail of the SRT file) so as a user we can see it's still working through the file and not that the process is hung.

I know we could modify the chapterize_ab.py#760 and remove the -loglevel quiet arg and see that it's working but if a prettier option was available it would be nice.

Hello, thank you for the feedback. The reason I left it out is because it clutters the UI (and most people don't care about the output, frankly) but I'd be happy to add a switch to the CLI args that does this.

I'm in the middle of a massive overhaul to the app (that keeps getting interrupted unfortunately), so as soon as I get some free time (there hasn't been much lately) I can add that in with the rest of the features.
