rust-hg-core: upgrade dependencies

This upgrades all dependencies to their latest version, except `clap` and `zstd`
whose latest versions do not support our minimum supported Rust version 1.48.0.

Same as for `rhg`, it contains security fix for `regex` which does not affect
us too much, but doesn't hurt, and the rest of the upgrades are there simply
to keep up.
