Bump itertools to 0.13

Is there any particular reason?

I'm working on packaging this for Alpine Linux and have found that Cargo.lock has not been updated for a while, so some architectures don't compile. Also it's usually good practice to install things using cargo install [package] --locked, so regular users are probably getting old packages too. I've decided to start by bumping crates that have new semver incompatible releases and then send another PR at the end for Cargo.lock.

I see. The counterpoint is that newer packages tend to have higher MSRVs which can cause different problems for some people.

I'll be more willing to take these if you can share that e.g. itertools 0.12 doesn't build on riscv or whatever it is.

I think it makes sense given especially the recent conversation on rustls bumping MSRV in a security release. I don't see itertools as one of those packages since:

1. Their current MSRV is 1.43 and their only dependency is either with a MSRV of 1.37 - they both check MSRV on their CIs - they could almost run on the dead Debian 10
2. They don't seem interested in bumping MSRV Update some of itertools' dev-dependencies to their latest versions rust-itertools/itertools#986 (comment), although an explicit policy does not seem to exist

As for my other two PRs:

nix is supported on Rust 1.69 and higher. Its MSRV will not be changed in the future without bumping the major or minor version.

I was going to say good things about cargo_metadata, since at least by their incomplete changelog they seemed to bump MSRV just on minor versions, but then I discovered that they bumped MSRV in a patch release two days ago in response of their dependencies also bumping it 🤷‍♂️ ¹. There are crates like hyper on the other hand that still support 1.63 even though the latest tokio release does not because the LTS release (one of the few crates that has one) still supports it.

1. I think it could be talked about with the maintainer https://github.com/oli-obk/cargo_metadata/commit/eae17fb2da575e3e4cc91213718b284cb32d4b2b ↩
