OGGPRE - Universal Precompression based on LibVorbis

[panker1992]

This project begun quite a few months ago, its based on a rust project OptimFrog.

It enables lossless compression for OGG and Opus files.

i have managed to pull a hefty bump from my previous version from 12% ratio to up to 19% on certain cases.

And for OPUS up to 5.5%. it comes with certain slowness nonetheless.

it has backwards compatibility with my old format OGP3. and it can decode or decode that as a result.

Note: this is a technology demo, to compensate for the weakness in speeds you can find this embedded inside my Archiver, which multithreading and reverse checking is enabled by default.
