Type overhaul

• Fixed types of handlers for newer versions of TS.
• Returned reducer takes AnyAction.

TYPE BREAKING CHANGE: generic params have changed. You should remove any explicitly passed generic params and instead rely on inferring from the types of the handlers e.g.

createReducer<string>({
  foo: (state) => state
})

Becomes

createReducer({
  foo: (state: string) => state
});
