Generate every coordinate that fits a set of per-digit constraints. Pin each digit of an
N dd mm.mmm W ddd mm.mmm coordinate to a fixed value, a list of alternatives,
a range, or a back-reference to an earlier digit — then list all matches (up to 5000),
optionally filtered to within 2 miles of a point or to a permutation of a known coordinate.

How to fill a field
All fields are mandatory; an empty field is treated like 0-9.
- Hard coded — e.g.
5 - Alternatives — e.g.
5,6,2,1,4 - Range — e.g.
4-7 - Leaving blank means
0-9 - Reference — e.g.
F(references always have to point to a lower letter in the alphabet)
