Subject: [PATCH] sunvox: Refactor

- Use autoPatchelfHook instead of manually patching Linux binaries
- Support more platforms (ARM Linux, Darwin)
- Patch more binaries (x86_64 & aarch64 has sunvox_opengl variant, other Linux platforms have others / even more)
- Support JACK
- Add myself as maintainer
