use-reducer hook supplies arguments to the reducing function in the "wrong" order

[cjsauer]

Was just bitten by this and it took a bit of debugging. React's own signature for the reducing function passed to useReducer is reducer(state, event), however Rum's wrapper for the hook is reversing the order of these parameters:

rum/src/rum/core.cljs

Line 528 in 75174b9

(.useReducer js/React #(reducer-fn %2 %1) initial-value identity)))

Was this accidental? It's unfortunate that it doesn't match the signature of the underlying React hook, but also that it doesn't match the signature of Clojure core's own reduce.
