Unit number prefix treated as unit number suffix

[mraross]

Here's an address that has a unit number prefix:

UNIT A101 -- 17780 56 Ave, Surrey, BC

This would be transformed by data prep into the following:

UNIT 101A -- 17780 56 Ave, Surrey, BC

This is incorrect. In Canada Post standard, A101 is treated as a unitNumber. In other words, CP allows a character at the beginning of a unit number to accomodate building names as letters.

As it turns out, we do allow an optional single character at the beginning of a unit number. A valid example is UNIT J205 1400 ALTA LAKE RD Whistler BC
