Adds `audio:format`, the audio track's four-character codec identifier from the MP4/QuickTime sample description (e.g. `mp4a` for AAC, `alac`, `ac-3`). `TikaMp4SoundHandler` already reads the sample-entry format fourcc (it uses it to detect `drms`/`enca` protected streams); this exposes it as metadata. For protected streams the original codec is recovered from the nested `frma` box, with `audio:has-drm` still set. `xmpDM:audioCompressor` only fires for audio-typed files and carries the container brand, not the per-track codec, so it doesn't cover `video/*` files. Verified against the M4A test fixture (`mp4a`); metadata schema registries updated. https://issues.apache.org/jira/browse/TIKA-4838 Follows TIKA-4779, TIKA-4800 and TIKA-4802. -- This is an automated message from the Apache Git Service.
