Case contract

Input a normalized uppercase line. Tokens in the keep set (PO, NE, NW, SE, SW, N, S, E, W, RR, HC) stay uppercase. Tokens starting with a digit keep the digits; an ordinal tail ST/ND/RD/TH is lowercased, any other tail (a unit letter) is kept. Other tokens are capitalized per hyphen part and per apostrophe part, and a part starting with MC is written Mc plus a capital.

Why this case matters

Normalized addresses are stored uppercase but printed on customer-facing documents; wrong casing of ordinals, directionals and unit letters looks like a different address.
