Adding geocoding HABS/HAER/HALS project

[SabrinaTT7]

This will add the notebook and supporting files for the geocoding project with HABS/HAER/HALS

I think this looks great! This will be the perfect notebook for us to link to for anyone trying to use our collections from a geospatial perspective. I only have two relatively minor notes on formatting and these are just my opinion/suggestions and not a rule:

Where possible, print data as a table using Pandas. In some cases, the data will need to be transposed, e.g.

Generally, I like to have some kind of output within a single code block. This gives me some feedback if I am executing each block manually. E.g.

Similarly, I may want to see progress in a loop that takes longer than ~10s, e.g.

Otherwise, this looks good to merge when you're ready!
