Subject: [PATCH] Update vtt.c cue_settings uninitialized variable

Error    C4703    potentially uninitialized local pointer variable 'cue_settings' used ... libcaption\src\vtt.c    278

Though all code paths seem to initialize it. `parse_timestamps` always fill it in. And when that is called, `block_type` is set `VTT_CUE` which is the only path that uses it afterward.
