Treat the byte[] as an unsigned series of bytes, most significant bits first. Start by adding 1
to the rightmost bit/byte and carry over all overflows to the more significant bits/bytes.

@param input The byte[] to increment.
@return The incremented copy of "in". May be same length or 1 byte longer.
