feat: fetch crate versions and deps using sparse registry index (#137)

* feat: [WIP] fetch crate versions and deps using sparse registry index

* feat: correctly handle `dep:<crate_name>` features in popup

* feat: correctly handle `dep:<crate_name>` features in completion

* refactor: remove unused function

* chore: update todos

* refactor: clean up feature toggling

* feat: fetch missing metadata from api

* refactor: rename misleading variables

* fix: version, feature, and feature members sorting

* test: update json_spec

* fix: rely in api version ordering instead of manually sorting

* fix: don't allow twice as many parallel requests

* test: add Cargo.toml with tricky dependencies

* fix: add missing default feature at first position
