v1: functional sound recording on all platforms, works with Blender 4.4

Version 1 is officially released! 🎉

Shiny and New

• Tested to work with Blender 4.4 and 4.5.
• macOS: use atunc, a new utility to record sound, instead of ffmpeg.
  This fixes the severely glitchy sound and comes bundled in the add-on so no external
  dependencies are required. (#6)
• macOS + Linux: show improved microphone names and description in the UI.

Fixed

• Audio recording off-sync by aligning the sound clip with the end instead of start time of the recording.
  Sometimes the sound clip is shorter than the time since starting to record due to latency in
  starting the recording process. The latency depends on the hardware and OS and can happen either
  with atunc of ffmpeg. In our testing it was most often less than half a second, so we consider it
  acceptable for the purpose of recording scratch dialog. The sound should now be added in sync with
  the edit.
