pkg-config, and mutli disto compiling

[spooketti]

sidenote: this allegedly works great https://github.com/thesyncim/gopus and doesn't require anything

right now there is an issue when compiling the source code that users need pkg-config for opus

this is non ideal as relay while having a technical theming is not meant to be difficult to use or obtain

a pkg-config install is a hurdle in the long run which requires one of the following solutions

1. keep things the way they are and distribute a binary that has a static link to opus [users who compile from source have to have pkg-config]
2. find some workaround to compile without pkg-config while continuing to use hraban opus [static link also required]
3. rewrite in gopus

futhermore, there is currenlty no methodology written down for compiling across OS (windows, macOS, linux are all that will be "required")
