chore(deps): bump mp4ff to v0.55.0 and go-608 to v0.7.0

mp4ff v0.55.0 adds AV1 metadata OBUs and CTA-608 caption carriage for AV1, SEI NAL unit encode helpers, tkhd matrix preservation, Motion JPEG support and dec3 JOC detection, and fixes several parser panics on truncated SEI. Its CEA-608 to CTA-608 rename in the sei package is a breaking change upstream but livesim2 does not use that package directly, so no code changes are needed.

go-608 v0.7.0 assigns caption payloads in presentation order rather than decode order (Eyevinn/go-608#54), which livesim2 already does itself in injectCC608, so the served bytes are unchanged. It also delegates the SEI wire format to mp4ff with byte-identical output, and adds AV1 carriage plus carriage.SpliceSEIBeforeVCL and generate.WithFlipAtCueStart, both of which livesim2 now duplicates locally and can adopt separately.
