Media: Opus, Ogg, MP4 and Matroska come from craft-libs (#2047)

DeckCraft kept its own Opus decoder (crates/opus) and Ogg demuxer
(crates/ogg), and two crates that only re-exported craft-media
(crates/isobmff, crates/matroska). craft-libs has all four: craft-audio's
opus module and craft-media's ogg, isobmff and matroska modules. The four
crates are removed and crates/media depends on craft-audio and craft-media
directly.

craft-media and craft-audio are pinned at 113f2360, the head of craft-libs
#810, which carries the two Ogg fixes DeckCraft made to its own copy
(51d19baa, 9d36b593). The pin moves to craft-libs main once #810 merges.
craft-pdf, craft-update and craft-ui keep their pins.

One API difference: craft-media's OpusTiming::of saturates on a hostile
granule position instead of returning an error. The end-trim product in
the Ogg Opus decode now saturates as well; a test with a three-channel
file and the largest granule panicked on it without that.

crates/bitstream stays: it also holds the video decoders' memory budget,
which craft-libs does not have.
