Read the zone lists in the country file

The # blocks in wl_cty.dat list CQ and ITU zones by call area and the first letter after the digit, written with the main prefix letters. A call now takes them whatever its own prefix letters are, so RA9Y and RM9I get what UA9Y gets, as in N1MM. A call whose own prefix rule gives a zone, and a whole-call entry, are left as they are.
