Since the latest published version of rnix-parser on crates.io, the crate has undergone major changes which are only available in the git repository at the moment. This commit updates the compiler to this newer version of rnix. Most notably, the entire AST provided by rnix is now wrapped in the AST type system. As a result of this traversal is much nicer in many places, especially for things like nested attribute selection. There are a handful of smaller features missing for full feature parity with the previous version, especially handling of path literals, but PRs for these already exist in rnix-parser.
