Get station data using get_data() function

[nicolejkeeney]

Summary of changes and related issue

Added the ability to retrieve station data using get_data() function. Also added the ability to see weather station options using get_subsetting_options().

Relevant motivation and context

These functions were unfinished without station data. Plus, Victoria needs this functionality for some code she’s writing for an IOU.

How to test

Run the notebook climakitae_direct_data_download.ipynb in the branch get-station-data in cae-notebooks. At the bottom of that notebook, there’s some code related to how to use the new functionality from this branch. Try retrieving some different stations, resolutions, etc. Make sure the error messages make sense when you put a bad input, and that the data that is retrieved matches what you input in the function arguments.

More a comment here:

My one big thought here is that for data_type the response is "Stations", while for get_subsetting_options the area_subset response is "Weather stations". Is there any reason we can't make those both "Stations"?

Otherwise, no issues retrieving, got some nice errors with bad intentional typos, especially with more than 1 station input providing "did you mean this" for both!
