location-importer: Replace ARIN AS names source with one that offers human-readable names

This patch replaces our previous source for AS names in ARIN's realms
with another file provided by ARIN that contains human-readable names
for organizations ASNs have been allocated to.

Please note that a

	TRUNCATE autnums;

is necessary on machines previously running the old version of
location-importer, in order to make use of this changed data source.
