update gix to the latest version

[Byron]

Please note that I have removed the max-performance-safe feature
which pushes the choice to the consumer of (any) library that uses
gix. It's also causing less C to be compiled by default.

Description of Changes

An upgrade to the latest gix, which includes less dependencies now and compiles a little faster
because of it. It also avoids making decisions about performance (and the inclusion of C-crates)
by removing the max-performance-safe feature.

The motivation for this update is to get a new tame-index release for consumption in this PR
so that it can also use the latest gix version without duplication.

Thanks!

Oh, so the clippy lints are real - I thought this can't be as I have simplified and boxed errors rather than making them more complicated. I typically address these by ignoring the clippy lint, but maybe in this case, it's better to box? Please advise :).

Finally, you might be interested in a new line of conversation that will hopefully lead to a complete revamp of error handling as a mix between anyhow and thiserror: therror :D. Let's see if it happens, I surely hope so.

But definitely interested to see what you can do for errors in future revisions, it is a bit of pain point with gix at the moment unless one goes the lazy anyhow route.
