Add support for old RIFF formats

[tanabotadtx]

Although I didn't clone/build new NX, but if this BGM can't playback after removing SoundDecoder,

we'll need to apply

Note: fix contains NVorvis project, and it requires .NET Core SDK to build... (ticket says so).
It's too big too apply...

As described by @ericpignet in #55, bjxa is the replacement library for the XA file formats. This is to reduce dependencies on external libraries. See libbjxa in the latest PR #59. Tested with given XA files and working as intended.

Just checked with @freshcoool, please avoid old classic charts as the bundled wav file is invalid. Tested with earlier versions and problem remains.

@tanabotadtx still has a point, DTXMania would not have introduced NVorbis for no reason.

From what I understand, some WAV files encoded as "mode 2+" by "Xiphophorus libVorbis cannot be decoded by Bass but could be decoded by the old SoundDecoder lib.
There is a workaround which is to remove a few bytes, or to reencode the WAV, but they decided to use NVorbis lib to handle these types of WAV files.
We may have to do the same if we want to support these classic charts with WAV instead of OGG.
