Lifetimes are anon

[gilescope]

The liftimes to the str and the &[u8;32] are all anon. If they were 'scale (i.e. linked back to the original scale &'scale [u8] slice) then people could use the visitor to do zero copy decodes.

This will be closed by #11, which uses a touch og GATs to allow zero copy decoding.
