/**
 * SSH 2.0 binary decoder for SSH protocol data types.
 * Implements SSH binary decoding according to RFC 4251.

 * Key SSH decoding principles:
 * - Multi-byte quantities are transmitted in big-endian byte order (network byte order)
 * - Strings are length-prefixed with uint32
 * - No padding is used (unlike XDR)
