ESRI source fails quietly sometimes about machine HOT 6 CLOSED

The Python ESRI scrape code runs through OBJECTID's 500 at a time. Sometimes the source's OBJECTID first value is > 500, so the scrape returns zero results.

I should probably start off the scrape by doing an OBJECTID search from 0 to 1000000000 or something and then go from there.

I take that back. I'm assuming the column is called "OBJECTID" when in fact the oid column could be named something else. The name will be in the metadata for the layer so I'll query that first.

Hmm, I've tried a few sources after integrating your pull request #41 and still no joy. My repo is at f28c27f and us-sd us-al-calhoun us-sc-berkeley all still seem to find no features.

Oh btw here's how I'm testing stuff, after doing a pip install.

openaddr-process-one ~/src/oa/openaddresses-me/sources/us-al-calhoun.json /tmp/
wc -l /tmp/us-al-calhoun/out.csv

I've verified us-va-city_of_norton and us-wi-vernon now work. Also us-wy-albany still works, to name a random ESRI source that was working before #41 and #44 were merged.

us-al-calhoun ran for about 10 minutes getting valid-seeming JSON and then barfed with a DownloadError, but that's likely to just be a failure of their web server (see below for details). We'll know more after the next bulk run. Closing the ticket, nice work @iandees!

The issue you're seeing there @NelsonMinar is fixed in #45.
