Add Geopandas.GeoDataFrame Document Loader

[brendancol]

Work in Progress. WIP Not ready...

Adds Document Loader support for Geopandas.GeoDataFrames

Example:

• [x] stub out GeoDataFrameLoader class
• [x] stub out integration tests
• [ ] Experiment with different geometry text representations
• [ ] Verify CRS is successfully added in metadata
• [ ] Test effectiveness of searches on geometries
• [ ] Test with different geometry types (point, line, polygon with multi-variants).
• [ ] Add documentation

@brendancol this is awesome, do you have an example use case and data in mind to demo? Happy to help put together a jupyter notebook.

I'd also love this feature! 👌

@zzsi great idea. I'm going to carve out some time this week to experiment with this document loader.

For tracking purposes:

• [ ] Add Jupyter notebook example using default geopandas datasets

I've used Geopandas in the past and am a fan! Can help get this in.

Looks like we need a notebook.

Added example notebook that shows how to create geopandas DF and then load it.

A use-case example showing chat over structured data that includes lat, lng would be fun.
