Added cross-references between FCC CDBS facility ID numbers and their respective Mexican facilities in the IFT data. Completed AM data previously started and did the entire FM band. Please note that the AM coverage is nationwide and that FM and TV coverages are only within 320 km of the border as those are the only facilities that IFT has to report to the FCC.
Added functionality to support FM complementary transmitters. These are same channel facilities in either shadowed areas (like boosters) or to expand coverage (like translators). Adding shadow transmitters remains a manual task (there are currently only two FM facilities with complementary transmitters).
