v2.7

This release removes private links (normal links are still there) and introduces a way of creating private keys by simply calling keygen with an "extendable" key (ie. a key with e permission). On top of that, it has a few optimisations and emitter now defaults to using/generating license v2 which was introduced a few months ago.

Changelog

• Added chunking before sending through to the gossi unicast, given that the max frame is 10MB we can send at once (#254)
• Added a debug mode flag in the config. Ppprof HTTP endpoints are now by default disabled and you'll need to flip the flag on to enable them (#255)
• Fixed a security issue by disallowing pub/sub on extended keys (#262) (#261)
• Added a way to extend keys through a normal keygen method. Users will need to provide a key which has extend permissions in the request along with the desired access permissions. Note that the permissions will be a reflection of the key itself (e.g: if a key has re permissions and keygen request contains wr, the resulting key will only have r permission) (#268)
• Upgraded the dependencies and made v2 license default. (#278)
• Removed private links as they have been replaced with a keygen. This is to make sure there's only one way of extending keys and keep the API relatively simple to understand. (#279)
