Implement Encode/Decode for &'a [u8]

[DrSloth]

This would allow bitcode to serialize/deserialize arbitrary bytes (like non utf-8 strings) to be serialized/deserialized without the serde feature

It's a bit tricky since u8s may be packed as u1 u2 u4 which can't be borrowed as u8 from input. It would require borrowing from a bitcode::Buffer after the u8s are unpacked.

Good point, would it be possible to provide some wrapper type that gets serialized as raw bytes? My specific use case actually is that of non UTF-8 text. I kind of need str encoding but not UTF-8.

In my case i could also implement the traits by hand but that doesn't seem to be documented.

And your use-case requires zero-copy for some reason? Otherwise you can use Vec<u8> or Box<[u8]>.

Hi guys,

Thank you for great framework! Would be nice to see that feature!

Thank you!
