MXF structural conformance

MXF structural conformance, SMPTE ST 377-1

What we measure and how

Parses the MXF file's partitions, header metadata, descriptors, multichannel audio (MCA) labels, index tables, DMS-1 entries, and ANC packets, then runs a battery of structural cross-checks: partition / footer integrity, header-vs-footer metadata agreement, operational-pattern classification (OP-1a / OP-Atom), edit-rate consistency between descriptors and index tables, MCA tag / link / language coverage, and ANC payload framing (SMPTE ST 436M). Findings are emitted as namespaced `mxf.<area>.<rule>` rule IDs (see mxfcore RULES). The IR is reused by `video_captions_present` to surface SMPTE ST 436M ANC captions that ffmpeg / ffprobe miss.
