run script for webmap geojsons

[danlewis85]

Description

This PR add a new run script /pipeline/run_scripts/run_make_webmap_geojsons.py and some associated keys in the config file (under the webmap_data_source key).

Running this script produces a set of GB-level geojson files with suitability scores appended. The geojsons produced are at different levels of aggregation to allow for effective rendering at different levels of zoom.

Closes #74

Thanks so much for this @danlewis85 !

It looks good and I couldn't find any errors. I left some comments mostly re documentation, plus some minor suggestions.

I would suggest moving your functions in this script into some utils files. We can make a separate issue for this if easier. I think they could be useful for other stuff as well.

Also, some of the functions could be renamed to be clearer. Our repo style guide suggests the following format for readability: action_returnsType_description e.g. check_exists_str_file_uri instead of get_file_uri.

Question - is there a separate script for the geojson creation and simplification which needs review?

Thanks so much :)
