Remove direct dependency on Pathom 2

[awkay]

Follow the pattern in the latest commit of RAD (see attributes and resolver ns) to make it so that this library has no direct need for Pathom 2. The artifacts of P2 are all maps, so there should be no need to make externally visible API changes to do this.

Locally (ie. I haven't committed) there's now no direct need for P2. However I need to take my lead on this issue from fulcro-rad-datomic. This code (fulcro-rad-kvstore) includes a copy of a recent fulcro-rad-demo. Currently the latest fulcro-rad-demo depends on an old (1.0.9) version of fulcro-rad-datomic. I'd like to see 'everything working at latest'. The specific problem: pathom-plugin now has 2 args, with connection->db being the new 2nd arg. The demo doesn't yet call pathom-plugin with 2 args (in com.example.components.parser).
