Planned features for cargo-install v2

[baptiste0928]

I plan to work on a new major release (with breaking changes) soon.

• [ ] Support cargo-binstall for even faster crates installation. :rocket:
  • Add a binstall input to decide whether cargo-install should be used (defaults to true).
• [ ] Support a version shorthand in crate input (e.g. [email protected]).
• [ ] Support installing multiple crates at once (separated with spaces). See #4.
• [ ] Force usage of secure transport protocols for all requests.
• [ ] Set locked to true by default to prevent sudden CI failures.
• [x] Update to Node.js v16.
