Make the 3 times check of TS packet sync byte as optional

[EKW12345]

Is your feature request related to a problem? Please describe.

After version 1.4.0 extra checks were added to verify that the ts packets in the start of the segment, contain sync byte. The commit describes that it was added following to false possitives. We use hls.js to play a hls stream that played well in the old versions of hls.js and since version 1.4.0 it crashes following to exception that says that thousands of ts packets without sync byte were found.

Describe the solution you'd like

Make make this triple check of sync byte optional by configuration.

Please share an example using the latest release of hls.js.

I would prefer to address this via a bug report than supporting a config option for legacy behavior.

Hi @EKW12345,

I expect this issue to be resolved in v1.5.0 with #5858. You can verify the fix in v1.5.0-alpha.1 or the latest dev build.
