Implement CI and release logic

[jrozner]

Actions should be setup to do builds of PRs and the main branch. Also need to setup some release logic to do builds of the library itself so that people can just install it without having to compile themselves. There probably should be some branching strategy that maps to binja release versions to get builds going for each supported version of binja and probably decide how far back I want to actually continue to support.

Basic CI is added with actions but there is no release logic or branching logic in here. The build environment needs to setup binja and an environment to build in.
