update gix to the latest version (#27)
Browse files Browse the repository at this point in the history 
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.

### Checklist

* [x] I have read the [Contributor Guide](../../CONTRIBUTING.md)

Conduct](../../CODE_OF_CONDUCT.md)

included in the section below

### 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](obi1kenobi/cargo-semver-checks#531)
so that it can also use the latest `gix` version without duplication.
