Following earlier discussions with Satsuki the precedent we set with
these packages didn't make sense when applied to token manager. We're
probably stomping on a wider namespace than we'd ideally like but thats
a common theme across rust package names at the moment plus its
possible we'll roll both these into token manager at some point anyway.
