`hexx v0.10.1` introduces breaking change for pre-rust `v1.71.0`

[orph3usLyre]

A change introduced by PR #114 will prevent hexx from compiling with rust versions prior to v1.71.0

This is because the implementation for impl<T> From <(T, T)> for [T; 2] was only stabilized in rust v1.71.0

This is the code block that causes this issue (src/hex/convert.rs):

impl From<(f32, f32)> for Hex {
    #[inline]
    fn from(v: (f32, f32)) -> Self {
        Self::round(v.into())
    }
}

Perhaps update/mention the MSRV for the crate or rollback the change for backwards compatibility?

Indeed that may be a problem, I don't know what would be the best way to handle that, maybe I should use the msrv attribute in the manifest.

@alice-i-cecile You are more experienced in OSS than I am, what would be your preferred way of handling this kind of problem ?

[alice-i-cecile]

My preference here is to include the MSRV in our Cargo.toml.

If you want to be particularly by-the-books, you'd yank any published releases with this undocumented semver-violating change, and bump the major version when your MSRV is updated.
