Searches the blocks for the given address bits. Returns a list

geocoded_pt will be None if number is None.
We make these assumptions about the input:
* Everything is already in all-uppercase
* The predir and postdir have been standardized
Note we don't enforce parity (even/odd) matching.
So 3181 would match the block 3180-3188.
