matroska-go

Refactor VINT reading in EBMLReader to skip padding bytes for improved synchronization. Enhanced error handling for invalid first byte.

Enhance test coverage for Matroska parser and demuxer. Added edge case tests for seeking behavior, cue handling, and error scenarios. Improved handling of nil fileInfo in GetLowestQTimecode and refined cluster header parsing tests.

Standardized time processing in SRT conversion to use nanoseconds for increased granularity. Updated parameter documentation and internal logic accordingly. Replace hardcoded input file path in example code with specific test file reference intended for local testing.

Add seeking and cue-aware navigation to Matroska parser
