Seeking a HLS video desynchronizes subtitles

[fir3z]

As the title suggests, there appears to be a bug that causes subtitles to desynchronize from the video if the video is using HLS & has been seeked through.

Here's what I've tested so far:

• Syncs if HLS video without seeking
• Desyncs if HLS video and seeking
• Syncs if MP4 video without seeking
• Syncs if MP4 video and seeking

this isn't an issue with jassub

this is definitely an issue with the HLS library you use, not jassub as jassub uses the video's currentTime to get the accurate timestamp for rendering subtitles, either fix this inside the HLS library you use, or use JASSUB's time offset to set a proper time offset yourself
