ww2ogg 0.24

Now supports --no-mod-packets and --mod-packets to override the detection of modified packets.

The oldest known AudioKinetic Wwise Vorbis file is now supported, from 2008's KetnetKick 2.

ww2ogg 0.22

Biggest change is removing the "unknown chunk" error, ww2ogg now happily ignores unknown chunk types.

Also a few build adjustments, avoid pulling in too many dependencies.
