Shall there be option to also install cargo-clippy

[vi]

It is a bit untrivial (need symlink, just cargo install fails) and also requires updating when nighly updates.

Maybe multirust should have explicit easy cargo-clippy support to correctly install cargo clippy command and keep it afloat when updating nightly?

There may be reasons for mulmtirust pre-install certain Rust tools, like clippy, and rustfmt. For example, I'm intending that multirust-rs will pre-install a cargo plugin for managing native toolchains. That case is somewhat special though because it needs direct multirust integration.

I don't think I'm ready to open the floodgates yet though and install other arbitrary cargo commands.
