Add slice-based methods to FromBytes

[newpavlov]

Right now slice conversion methods are somewhat buried in Ref. For better ergonomics and discoverability I think it's worth to have the slice-based methods on the FromBytes trait.

Thanks for this!

Done! I've used [`FromBytes::slice_from_prefix`] instead of [`slice_from_prefix`], but I can replace it to [`slice_from_prefix`](FromBytes::slice_from_prefix) if you prefer it.

Oops, just saw this. Yeah, that'd be preferable, thanks!

Okay, looks good! Could you update Cargo.toml and zerocopy-derive/Cargo.toml to bump the version number to 0.7.24 so I can release this once it merges to main? There are four locations you'll need to update in Cargo.toml and one in zerocopy-derive/Cargo.toml.

Done!
