Dear Rust Maintainers,

the version of Cargo seriously needs an update. Because the word is
moving and the old version performs increasingly bad.

I.e. we got Rust 1.70 in the meantime, and there were more fixes in Cargo.
Also sparse mode is now enabled by default, see
https://releases.rs/docs/1.70.0/#cargo while in the version 0.66 the
sparse mode seems not to work if configured manually. And the index
update is also NOT smart in the old version, meaning that it rebuilds
quite often, and then it takes OVER SIX MINUTES on my laptop (older Core i5).

I tried manual update of cargo ("cargo install cargo") and the new
version shows "lightspeed" performance compared to the old one. Also the
required space for metadata in ~/.cargo/registry/index went down
from >> 700MiB to a matter of a few hundred KILOBYTES.

Best regards,
Eduard.
