use upstream version of 'macaroon' crate

The code changes are pretty minor: using default() instead of new(), and
(safely) parsing bytes out of predicates instead of getting String
directly.

The validate() function is now run automatically as part of
deserialization, so don't need that function call.

This reduces duplication in the dependency tree, and gets us on sounder
footing for maintainability, which is great!
