Subject: [PATCH] chore: remove unused rustc-hex deps; enable rustc-hex for
 primitive-types in sp-core (#4860)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some primitives have impl Hex related traits enabled by `rustc-hex`
feature. People wanna use H256/H160 maybe need these trait impls
