Doesn't generate uses edges for fully namespaced components

Hi @asomers, and thanks for the report! You are absolutely right in that this is currently an unfortunate limitation.

The rust-analyzer API that cargo-modules currently uses for obtaining the dependencies only seems to include explicit imports. It also currently only works on module level. As such cargo-modules currently can't tell you the dependencies of say a type or function.

I'll have to see if there is some alternative function in rust-analyzer that provides a more complete picture.

I thought it was something like that. If it can't be fixed, cie la vie.

I'm fairly certain there should be some way to get this information out of rust-analyzer. I just couldn't find any function that directly addresses cargo-module's needs.

I'm somewhat hesitant to asking the rust-analyzer for help as they are already generous enough to share the internal unstable APIs with third-party tools like cargo-modules. Effectively asking them for free user support on top of that feels a bit wrong to me.

Fixed by #227.
