For fetching land data, handle redux state on request made, request successful, request failed, etc.

We are fetching land data with hardcoded data in the demo app already - just not by dispatching an action. But it's TBD whether we want to get it via dispatching an action using thunk or saga. We may or may not want to go that route for data fetching

Note that “action” as used here is in the redux sense of the word, not the “Tasit action” sense

@marcelomorgado I reworded the name of this issue so it wasn't a duplicate with https://github.com/tasitlabs/tasit/issues/20
