That certainly makes sense to me. At this point, the only reason that would not work is an arbitrary limit of 255 on the input, and the only reason that limit is there is to have `bchr` be the inverse of `ord`. Since `bchr` isn't going to happen, I see no reason to have the 255 limit. `byteorder` can default to None with a requirement of being set when the integer is over 255.
