> ByteRange is a useful alternative to Java's ByteBuffer. Notably, it is mutable and an
instance can be assigned over a byte[] after instantiation. This is valuable as a performance
consideration when working with byte[] slices in a tight loop. Its current design is such
that it is not possible to consume a portion of the range while performing activities like
decoding an object without altering the definition of the range. It should provide a position
that is independent from the range's offset and length to make partial reads easier.
