`gix_mailmap::Snapshot` does not implement `Debug` or `Eq`

[emilazy]

Summary 💡

It would be nice to be able to print and compare .mailmap snapshots for equality. Ideally the semantics would be the same as with .entries(), but without allocating a new Vec.

Motivation 🔦

I would like to include this type in types that #[derive(Debug, PartialEq, Eq)] for jj-vcs/jj#3951, and it just seems like generally‐useful functionality to have.

Thanks for letting me know!

Is this something you'd like to submit a PR for? If not (or it's more complicated), I am happy to pitch in.

[emilazy]

I can try to find the time to take a look once I’ve popped enough other tasks off the stack. But maybe just #[derive] would work here? It might not produce the prettiest output for Debug, though.

[Byron]

Alright, a PR is up, and the debug print should be fine (it's just a Vec internally).
