Improve handling of semver incompatible crates/packages
Rust allows a dependency tree to use different versions of a crate, including semver-incompatible versions. This should be reflected in determining what dependencies need to be packaged to support a crate.
Similarly, Debian may have multiple semver-incompatible versions of crates packaged in order to ease transitions from one semver version to another.
This MR updates the Packages parsing, reporting of packaged versions, and calculation of dependencies to take these factors into account.
As an example of the difference, here are the before/after for Alacritty v0.12.2.
