Add support to Cargo (Rust package manager)

[guibranco]

It would be nice if we have support to Cargo packages (Crates.io), so we can navigate from Cargo.toml file to it's Crates.io .

Example:

[package]
name = "hello_world"
version = "0.1.0"
edition = "2021"

[dependencies]
time = "0.1.12"
regex = "0.1.41"

Time and regex should point to:

• time
• regex
