Remove unused deps from workspace Cargo.toml

[utkarshgupta137]

Currently, cargo-machete doesn't check if the workspace Cargo.toml contains any unused deps or not. I think it should be straightforward as you only need to deal with Cargo.toml files, although things never are.

@bnjbvr any idea on this issue?

Yep, it's not implemented; one would need to scan the set of dependencies from the workspace, and then figure out the workspace definition to navigate through all the directories it includes. Good luck :-)
