specification allows the initial length to take up either 4 bytes

bytes describe the length and all offsets will be 8 bytes in length

+ An older, non-standard 64-bit format is also handled by this

+ format. As written, the code can't detect (old format) lengths
+ greater than 4GB. If it becomes necessary to handle lengths somewhat
+ larger than 4GB, we could allow other small values (such as the
+ non-sensical values of 1, 2, and 3) to also be used as escape values
+ indicating the presence of the old format.
