Reproducible builds

Hi! This issue is about getting Kiss to compile without worrying about Cargo dependencies. I have two suggestions:
1. Use `"rev"` in the dependency sections of `Cargo.toml` to pull in the specific versions of dependencies that work with the current revision of Kiss.
2. Tag stable revisions of Kiss with git tags. Use semantic versioning like `v1.1.5`.

Keep up the great work! :+1:

Start by reviewing the dependency sections in Cargo.toml and how this repository currently records stable revisions. Check the existing release and tagging practice before deciding how the requested revisions and semantic-version tags should be represented. Done means dependencies resolve to specific working revisions and stable Kiss revisions are tagged with the requested versioning convention.
