hex-noalloc

This is a temporary fork of the hex crate, uploaded to make it usable for other crates that are uploaded to crates.io until #42 is merged.

It is a snapshot of the hex crate, with just that single PR merged. It will be yanked from crates.io once that issue is resolved and a new version of hex is released, at which point users are asked to depend on hex again instead.

Usage, examples, license etc.

Please refer to the original crate for this; other than the addition of the alloc feature merged from #42, all else is unchanged.
