feat(ci): add binary build and release workflow (#77)

This adds a workflow (or actually several parallel ones) that gets triggered for a new tag. It builds binaries for several different platforms, creates a release and attaches them as downloads. I wasn't able to make this work for arm64 (because of ring) therefore I commented that part for now.

Fix #59
