Distinguish between internal and external imports with :: prefix

[michaeljklein]

Problem

We can have a crate with a dependency foo but also a submodule foo. Rust disambiguates these with ::foo to select the dependency rather the submodule (or vice versa). We should have a test for this case in any case.

Happy Case

• Add :: prefix to parser
• Override case here to resolve externally when :: prefix is present
• Test here

Removing dep isn't important imo
