feat(mp4): decode QuickTime audio sample entries .mp3, lpcm, twos, and sowt

These QuickTime sample description names use the standard sound sample
description layout, but fell through to UnknownBox, so their channel
count, sample size, and sample rate were unreachable without hand
parsing. Register them with the audio sample entry decoder and expose
them as StsdBox.Mp3 and StsdBox.QtPcm.

Since these names decoded as UnknownBox before, a body that does not
parse as a sound sample description falls back to UnknownBox instead of
failing the file, and the StsdBox.AddChild type assertions for the new
names tolerate that fallback instead of panicking on it.
