950 	The quantity is described in the first byte.  If the MSB is zero, then the next seven bits
951 	are the quantity. If the MSB is set, bits 0-3 of the quantity are in the least significant bits.
952 	If bit 5 is set, then the quantity is further described in the next byte, where an additional
953 	7 bits (4-10) worth of quantity will be found.  If the MSB of this byte is set, then an additional
954 	7 bits (11-17) worth of quantity will be found in the next byte. This repeats until the MSB of
955 	a quantity byte is zero, thus ending the chain.
958 	If the MSB is set, then bits 5/6 describe the number of value bytes following the quantity bytes.
960 	encodings are: (q = quantity, v = value, c = quantity continues)
