ResponseParserInterface

Contract for the brand parser that turns a raw API response into its hash form.

Isolating the parse step behind this seam is the Response-tree twin of {\CNIC\TransportInterface}: a substitute parser can be handed to a Response (see {\CNIC\AbstractResponse::__construct()}) without reflection or subclassing, and each brand's real parser can be exercised directly instead of only through a fully constructed Response. The production implementations are {\CNIC\CNR\ResponseParser} (line-oriented key=value with PROPERTY[…] columns) and {\CNIC\IBS\ResponseParser} (JSON, falling back to plain text), used by IBS and Moniker alike.

The signature is deliberately uniform across brands even though only IBS reads $cmd — a contract the two could not both satisfy would be no contract at all. CNR's wire format is self-describing and its parser ignores the argument.
