Released the 0.38.3 version of the sysinfo Rust crate which allows you to query systems information.

This release improved the accuracy of system memory information on macOS.

PS: I know the current "lock" on the objc2-* dependencies is an issue. I plan to make a major release to release this constraint at some point (yeay minor semver releases which remove old(er) systems support...).
