v3.7.0 | Better Opus Library Support / New Audio Encryption Modes

The opus libraries used for encoding/decoding are now exported to their own dependency at opus-java. This allows for a smaller artifact if no audio encoding has to be performed by JDA (like just sending with lavaplayer).

You can find out how to exclude the dependency and consecutively decrease your classpath size by looking at the Download Section in the README.

We additionally now host a jar without opus natives on jenkins (suffix noOpus).

Discord has added new encryption modes to replace old ones, we now implement all currently supported encryption modes for audio. Additionally we reduced the amount of required allocations for sending audio, which should reduce garbage accumulation and CPU usage respectively.
