Paul Stemmet c4e514f6c2 lib/token: move Ref to token 
Ref is a type that allows us to discriminate between different lifetimes
specifically, whether the underlying Token is borrowed from the data, or
borrowed from the scratch space.

This buys us the ability to attempt zero copy deserialization, but fall
back to copying if required.

Paul Stemmet 0de27e1092 ci/clippy: fix error, allow styles

  so this style lint will be ignored
- On the manual range impl, inclusive ranges in Rust are slower than
  writing them out by hand by a significant amount
