chore: update deps

[CosminPerRam]

No major version changes, mostly patches including fixes and small performance improvements.

Thank you, a good catch!

We might want to consider to use dependabot for this - there is probably no good reason to not keep up with the latest versions.

[CosminPerRam]

For sure, will make a PR for this soon.

For a library crate, isn't the effect of these version updates simply to reduce the options available to dependent crates?

i.e. previously flate2 was compatible with any version of libz-sys >= 1.1.20, but now it requires at least 1.1.22. If, for any reason, a crate needs to keep libz-sys at 1.1.20, it now has a conflict.

I tend to update crate versions only when there is a security or bug fix reason to do so.

Thanks @jongiddy for chiming in and making that point.

To hammer home the "upgrades only when there is a need" idea, I think we'd also want to have a cargo audit job, probably as cron job, to get a heads up early.
There could also be a section in the README related to manifest update policies just to make it a little more official and accessible.
