Initial react-redux implementation: get an image rendering

[kadamwhite]

Yields

I've been struggling a bit with testing sagas, @gnarf -- if you have any bandwidth to review this generally (please don't hold back on the code review, tear it to shreds if you feel like it!) that'd be awesome, but if you don't I can muddle along if I can figure out how to fix this error when I run Jest:

 FAIL  src/redux/__tests__/sagas.test.js
  ● sagas › requestFacesSaga › yields an API call to get faces

    TypeError: (0 , _sagas.requestFacesSaga) is not a function
      
      at Object.<anonymous> (src/redux/__tests__/sagas.test.js:13:51)

Merging following review with @gnarf !
