Cue skipped when empty line follows timing in multi-line cues
When using webvtt.read(vtt_file_path) to parse WebVTT files, I've observed that if there is a blank (empty) line immediately following the cue timing, the actual subtitle text on the next line is not included in the output. For example:
00:02:36.420 --> 00:02:42.699
congratulations
In this scenario, the text "congratulations" is not parsed as part of the cue.
Reason
The current parser seems to expect subtitle text to appear directly after the timing line. If there is a blank line immediately after the timing, the parser treats the cue as empty and skips any text that follows.
Suggestion
The parser should ignore any empty lines that appear immediately after the timing line, and include all following non-empty lines as the cue text, to better handle cases allowed by the WebVTT specification.
Sample
As a multi-line sample, you can take this file to reproduce this issue.
