contains interleaved counties and cities, with code of form cc-nnn cc=county# nnn=city#
Can tell which city a county belong in by county ahead of it.  Also could use codes, but we don't.
Reshape to look like this:
#county/city              rate included state tax
Beaver county,             5.95
Beaver City,               6.95
Milford,                   5.95
Minersville,               5.95
Box Elder county,          5.95
