Add well locations to database

[mradamcox]

Well locations will be pulled from the data behind the Wisconsin DNR Well Construction Report Viewer:

The data will be copied locally, so that locations can be updated for more accuracy down the road. Therefore there are three general tasks here:

1. create db model(s) to store the well location data
2. write commands that will ingest data from the viewer to the karstography app (see this notebook for API testing)
3. set up map layers/interface

When these are accomplished, more can be done to add sample data, geological layers, etc. to each well.

All three items listed above have been achieved. This gives us a good basis from which we can begin to add more capabilities and data to the well locations.
