Patch Changes

• bbf55fe Thanks @DenizUgur! - Fix import paths and add a test to verify the tarball is installable.

  Release v2.4.0 upgraded tsdown, which apparently changed the output extensions from .js to .mjs and from .d.ts to .d.mts. This made the package uninstallable because the import paths were not updated. This patch fixes those import paths and adds a test to verify that the tarball installs correctly.

  fixes #561

Patch Changes

• #550 fdbdf11 Thanks @lideen! - fix: include nested QuickTime wave esds when deriving mp4a codec strings

• #543 a08dba1 Thanks @rbouqueau! - fix: tfra box parsing didn't allow to display all information

• #535 5b72b08 Thanks @dukesook! - add entry_count to saio box

• c6227fd Thanks @plantysnake! - fixes to pass 7 ignored test files from File Format Conformance

• #548 fe69a56 Thanks @lideen! - fix: reset fragmentation state on seek to prevent invalid fragment ranges

• #539 871def4 Thanks @dukesook! - warn if primary item id is invalid

• #550 fdbdf11 Thanks @lideen! - fix: normalize QuickTime wave esds in fragmented init segments for MSE compatibility

  By default, segmentation writes MSE-compatible mp4a.esds sample entries when source
  QuickTime files store AAC decoder config under mp4a.wave.esds. This behavior can be
  disabled with setSegmentOptions(..., { normalizeAudioSampleEntriesForMSE: false })
  to preserve nested QuickTime wave.esds sample entries in initialization segments.
