Sort station observations at lower layer; Add latest observation

Sort station observations to work around API bug weather-gov/api#474

This is probably the right place for this. Should we revert the changes in #60?

I noticed the test case, but I was a little confused that the Nws class was returning them out-of-order. I didn't think to look at the higher layer. It makes sense to me to have it in all layers (i.e., revert some of the changes in #60).

I added a method to retrieve the latest station observation to the API. Let me know what you think.

Note that I continued the general convention where the method name matches the NWS URI.

LGTM. Thanks!

This still LGTM if you are still OK with the ordering of the forecasts. We need to clean up conflicts before merging.

The forecast ordering matches your original workaround in simple_nws.py. Now that it's handled in the lower layer, I removed the sorting from simple_nws.py. I fixed the merge conflicts.

Thanks for removing the duplicated sort. One last comment and it is good to go.
