This solves a couple issues with crate2nix not matching expected cargo behavior. Fixes #387 and another issue where crates are located in subpaths of a git repository with no root cargo.toml. The second issue can be seen in https://github.com/strangelove-ventures/interchaintest where there is a rust crate located in
local-interchain/rust/localic-stdand no root Cargo.toml.Both issues can be fixed by making a list of all cargo.toml in the repo and checking to see if any of them match the expected name of the package in the workspace. This is possible because of a nixpkgs function
lib.filesystem.listFilesRecursive. This method seems pretty robust, since it follows the same logic that cargo itself follows when finding packages in a git repository as explained here rust-lang/cargo#1462 (comment).
