Bumped deps and now it fails lookup tests. Seems to be related to the hashable dep.
I need to look into if they should have passed in the first place though - the test expects the node to map to its self when looked up. I see no reason for this to be true given the guarrenties of the Hashable library. Hashring uses hashWithSalt to set the node mappings but hash to look them up, which of course uses an unspecified hash - perhaps varying from run to run. For consistency it should likely use a specified salt.
Use the salt 0 for lookups.
