Subtitle file(s) that ffmpeg and/or pysubs2 parse that subparse does no

[john-parton]

Here's a .srt file which both ffmpeg and pysubs2 parse without complaint, which subparse fails on:

1
00:00:06,000 --> 00:00:12,074
text1

2

2
00:11:49,412 --> 00:11:52,858
text2

Both ffmpeg's behavior and pysub2's behavior is to nest the extra line into the previous entry

1
00:00:06,000 --> 00:00:12,074
text1
2

2
00:11:49,412 --> 00:11:52,858
text2

I was working on a python binding for subparse and a file similar to this one triggered an error I wasn't expecting. https://github.com/john-parton/subparsepy
