Data integration automation: ITN range site prep

[BK01]

Convert the ITN range site prep script (step D5 in phase 2b) in the Geocoder data integration process from FME to Java.

This consists of a few separate changes. First the street prep is modified to include the address ranges in the street_load_street_segments.json output file. Then the Range generator reads these in and uses them to help define the new ranges (along with other site data). As a result, the step D5 FME script is no longer needed, and its output file "site_ITN_anchor_points.tsv" no longer needs to be read into the SiteLoaderPrep. Essentially the address ranges are turned into anchor points in the range generator so the skip over the siteLoaderPrep process entirely.
