Map shorthand unit names to their fully-qualified names

[NateShoffner]

ESRI uses shorthand unit names instead of of the fully-qualified names like the web/RSS feeds use ex MED865 -> MEDIC 86-5. With enough datapoints, this should be as simple as just building an internal mapping.

Going to document edge-case unit names with their respective fully-qualified names here:

Shorthand	Fully-Qualified
FMPSP	FIREMARSHAL PSP
LEBM12STA1	Lebanon medic 12 station 1
