Feature: Check for installed crates in cargo_install_v1_manifest (#582)

* Add & Impl new fn `CratesToml::collect_into_crates_versions`
   to iterate over crates listed in cargo_crates_v1, accessing their names
   and versions.
* Re-export `CompactString`, `Version` & `Url` in binstalk-manifests
   for convenience
* Fix `CratesToml::load_from_path`: Wrap `File` in `FileLock::new_shared`
   to avoid concurrent write while reading the file.
* Filter out installed crates in cargo_install_v1_metadata
* Make match in `filter_out_installed_crates` more explicit
* Add new test `cargo_crates_v1::test::test_loading`
* Optimize `CratesToml`: Use `Vec` instead of `BTreeMap`
  since we cannot simply call `BTreeMap::get` to find an entry for a crate
  anyway.
  This also accidentally fixed the CI.
* Impl new API `CratesToml::remove`
* Fix`CratesToml::append_to_path` by removing previous records of
   the crates that are just updated.
