Generated VTT files are not standard compliant

[KyleMaas]

When I first started using this program, I took subtitles and opened them in VLC and it looked fine. But then I tried another program, and they refused to work. Took me quite a while to realize that the output of AutoSub was actually not compliant with the VTT format according to this validator:

https://w3c.github.io/webvtt.js/parser.html

Errors I get include:

You are hopeless, RTFS. (10ms)
1. Line 2: No blank line after the signature.
2. Line 7: Cue identifier cannot be standalone.
3. Line 11: Cue identifier cannot be standalone.
4. Line 15: Cue identifier cannot be standalone.
5. Line 19: Cue identifier cannot be standalone.
6. Line 23: Cue identifier cannot be standalone.
7. Line 27: Cue identifier cannot be standalone.
[many, many more of these]

Unfortunately, I can't share the subtitles that did this. However, it happened with every file I tried. I was able to build a series of sed replacements to run on the AutoSub output file to make it so it passes the validator, but that's quite a hack. I'd recommend trying validation on a file yourself - it was consistently repeatable for me.
