Assign each ISD to an ESC

[coregis]

• [x] Check for ISDs nesting within ESCs
• [x] Assign each ISD to an ESC
• [x] Overwrite/update ISDs vector tiles on Mapbox

Assuming that they do nest properly, I can see two options for applying this as needed in the map:

1. [it sounds like this is your plan]: if you add an ESC field to the ISD tiles, I think I will be able to filter points by it as needed.
2. Or, if it's easier: if I can just get a list of the correspondences, I can declare that as an object in the javascript and use it as a lookup table.

Either's about the same amount of work for me, so it probably makes sense to do whichever is the path of less resistance on your side.

Yes, the ISDs nest within ESC regions! The path of least resistance (by far) was to create a LUT which I will add to the repo shortly
