do not exclude milemarker MM type addresses

This exclusion was meant to prevent matching residential addresses to interstate and highway addresses, but crime reports and other municipal reporting utilize these addresses and without them in cagis_addr() we can't match to them.

Holding for now. Impact of leaving out shooting and crime data at MM likely small.
