Layout was not actually needed, remove to simplify. Rename vgm_vorbis_info_t to ogg_vorbis_meta_info_t to clarify it's only for meta, also don't pass filename to init ogg (not useful even as an optimization since getting the name is a minuscule part in parsing a meta)

2017-12-10: Preliminary MOGG Support. As long as the stream is unencrypted, this should be fine.
|

This will also work on unconventional 5 channel Vorbis streams but some sound cards might not like it.

TODO (Eventually): Add decryption for encrypted MOGG types (Rock Band, etc.)
