Migrate clustering code to this repo

[RogerTangos]

@MichaelRyanWebber wrote some clustering code. It plays leaks and repairs in sequence, and then spits out a list of leaks where there was no repair nearby. It's clean code.

It needs to be moved into this repo and edited in a few ways:

• It work with the repo's file structure
• It should accept a ft/meter parameter for the radius of a repair's effectiveness
• You should be able to pass it the name of a repair and a leak file. (The geocoding scripts in PR Geocoding script for utility addresses #1 should spit this out.)

You'll want to coordinate with @ainzero on what sort of file format(s) clustering will ingest.

This is a good issue for getting familiar with the repo and code structure. It involves modifying a few parameters, but not doing too much coding.

• It needs to be able to ingest JSON files from the JSON folders.
• Specify what data will be thrown out. (i.e. what location_type)
• Save output, including metadata, like who ran it, when, etc.
