Help for maintenance

[Keats]

Hi,

I don't have enough time/motivation to work on this crate so i'd like to add a few co-maintainers. Anyone interested? I'll keep the crates.io rights to myself for now to check before pushing a new version still (so the none algorithm will still never be pushed for example)

One topic to discuss is https://github.com/Keats/jsonwebtoken/pull/377 vs https://github.com/Keats/jsonwebtoken/pull/318
