[Aoyumi]

Hi, everyone.

I released "aoTuV" beta6.03 (2018) of OggVorbis encoder and library (based on libvorbis1.3.6).

See http://www.geocities.jp/aoyoume/aotuv/

----------------------------------------------------------------------------
CHANGES (for general) from beta6.03 [2018]
# The latest aoTuV beta6.03 was unified with Xiph.Org's libvorbis1.3.6.
The part related to sound quality is not changed from previous version.
