* Refactor to support stabilized package ids This refactors the internals, and the public API, to support both the current "opaque" package ids as well as the new package id format stabilized in <rust-lang/cargo#12914> * Add test to validate opaque and stable match * Remove unused code * Fix lint * Update snapshot * Add docs
