* the integer fields comprising the UUID are stored as little endian values. If you want to pass such
* UUIDs to code which assumes that the integer fields are big endian (often also called network byte
* order), you need to adjust the contents of the UUID to e.g. achieve the same string representation.
*
* The required changes are:
* - reverse the order of byte 0, 1, 2 and 3
* - reverse the order of byte 4 and 5
* - reverse the order of byte 6 and 7.
*
* Using this conversion you will get identical results when converting the binary UUID to the string
* representation.
