KeyError in extract_color_nyc.py

Running make update today, I got the following error:

python3 scripts/extract_map_nyc.py
Traceback (most recent call last):

I'm guessing it has something to do with the color scheme of the DOH maps changing from orange to purple: https://www1.nyc.gov/assets/doh/downloads/pdf/imm/covid-19-data-map.pdf

This is actually not the problem with the color scheme, the problem is they are now sharing the data in terms of zip code district instead of "UHF neighborhood". The data point coordinates according to which the color is sampled is selected according to the previous criteria.

I am temporarily avoiding using this script and pondering whether there is the need to update the code/data because nycHealth are now sharing more detailed data in the official GitHub repo, in terms of zip code district.

If you indeed want to use this script, you need to prepare a new coordinates file like this:
https://github.com/chazeon/NYState-COVID-19-Tracker/blob/master/data/test_map_coords.json
which is originally generated using the WebPlotDigitizer.
