hearthstone-deck-format: mapping Hearthstone deck strings

hearthstone-deck-format documents the encoded deck strings used by Hearthstone. It breaks a base64-decoded example into header, hero, single-copy card, double-copy card and footer fields, and explains varint card identifiers. The author incorporated corrections from HearthSim's algorithms and includes Python format and parser files.
