Fix multistream packet corruption, implement GET_FINAL_RANGE for multistream, and add many tests. Multistream encode was failing to add the length of the extra length for self-delimited packets causing corrupted output. Multistream decode was not properly handling lost frames (and potentially reading out of bounds as a result). GET_FINAL_RANGE has been implemented as the xor of the final range of all the streams in the packet. test_opus_encode now does the mono narrowband tests using dual-mono multistream.
