What's the real MSRV for itertools?

[cuviper]

Currently, itertools documents MSRV 1.32, but CI only tests 1.36.

itertools/.github/workflows/ci.yml

Lines 11 to 19 in 7a27408

	msrv:
	name: Rust MSRV
	runs-on: ubuntu-latest
	steps:
	- uses: actions/checkout@v2
	- uses: dtolnay/rust-toolchain@1.36.0
	- run: cargo check --no-default-features
	- run: cargo check --no-default-features --features "use_alloc"
	- run: cargo check

The "use_alloc" feature does need Rust 1.36 for stable alloc. However, even with bare --no-default-features, Rust 1.32.0 fails on calls to checked_pow and saturating_pow, which were both stabilized in 1.34.

I ask because I'm considering MSRV 1.36 for the either crate to implement Future, rayon-rs/either#77, but I don't want to cause headaches if itertools actually wants to stay on an older MSRV.

It's just a documentation issue. Feel free to increase the MSRV of either to 1.36.
