Subject: [PATCH] Remove WebVTT handling code in gf_isom_dump_srt_track

Remove the code that handles WebVTT in gf_isom_dump_srt_track to avoid
needing to pull in a lot of other files from GPAC.

gf_isom_dump_srt_track doesn't appear to be used by ccextractor directly
or indirectly (it's only called in gf_isom_text_dump which doesn't
appear to be called anywhere else) so it should be fine removing it.
