Process repeated symbol code length. A) Check if it is the extension of previous repeat sequence; if the decoded value is not BROTLI_REPEAT_PREVIOUS_CODE_LENGTH, then it is a new symbol-skip B) Update repeat variable C) Check if operation is feasible (fits alphabet) D) For each symbol do the same operations as in ProcessSingleCodeLength PRECONDITION: code_len == B
