Title: 270/271 place of service code references 'pos' codeset

I changed the 270 and 271 maps to reference codes.xml:pos.

Inspired by receiving a '49' place of service code from Anthem Blue Cross in a 271 response, which is included in the 'pos' codeset but wasn't listed under the III02 sections.

One thing to note, however, that this codeset should only apply when III01 == "ZZ", but not when III01 == "BF" or "BK". I wasn't sure how to represent this properly.
