[Suggeston] Replace libvorbis with stb_vorbis

[RyanBram]

One of the goal of FluidLite is to become a lightweight replacement for Fluidsynth. As vorbis format is only needed for sf3 support, using libvorbis+libogg as additional library will make FluidLite become heavier. By replacing libvorbis with stb_vorbis it will get benefits such as:

1. stb_vorbis is more lightweight than libvorbis;
2. stb_vorbis has lesser dependencies than libvorbis (it only need itself without libogg);
3. stb_vorbis is licensed under public domain.

I don't have any programming skills so I am really sorry if I cannot help much other than giving suggestion.

Best regards, RyanBram

Might make sense to make SF3 support totally optional so vorbis isn't required at all? Then there will be zero deps?

[hanetzer]

I don't know. There is a good chance that a given project who would benefit from fluidsynth->fluidlite is already dealing with audio in various formats, and as such probably already needs libvorbis/libogg.

[MrSapps]

I think so too, which is why having it completely optional would be the nicest option IMO.

I added support for stb_vorbis in my fork. Also #17 is fixed.

Because my PR was merged, can we close this issue?
