SwiftMediaMetadata 3.0.1

Fixed

• Sony RTMD track discovery now skips top-level mdat payloads instead of
  copying the complete audio/video payload into memory. Structural boxes and
  file-absolute RTMD sample offsets retain their existing behavior.
• The real-world bare-JPEG fixture lookup now supports SwiftPM's current copied
  resource-directory layout, restoring a clean test run on newer toolchains.
• Release packaging now discovers SwiftPM's active binary output directory
  instead of copying a stale executable from a toolchain-specific build path.
