780     decode_rle decodes a single quantity/value run of a "modified-RLE" encoded
784 	are the quantity of bytes that follow that make up the run of value bytes.  (see case 0)
786 	If the MSB is set, bits 0-3 are the quantity's least significant 4 bits.  If bit 5 is set,
787 	then the quantity is further described in the next byte, where an additional 7 bits (4-10)
788 	worth of quantity will be found.  If the MSB of this byte is set, then an additional
789 	7 bits (11-17) worth of quantity will be found in the next byte. This repeats until the MSB of
790 	a quantity byte is zero, thus ending the run of quantity bytes.
792 	Bits 5/6 of the first byte, describe the number of bytes in the value run following the quantity run.
793 	These bits describe value runs of 1 to 4 bytes.  And the quantity describe the number of value runs.
796 	encodings are: (q = quantity, v = value, c = quantity continues)
