 1.4  20-Oct-2024  mlelstv When generating timestamp based GUIDs for reproducable builds
- increment timestamp by 100ns for each partition.
- use the standard time-based UUID format (type 1) and don't
pretend it's a random number (type 4).
- make the -T option actually work for the uuid command.

Random GUIDs:
start size index contents
34 1000 1 GPT part - d93ba067-a788-4ce0-99b8-0ead51f00215
1034 2000 2 GPT part - bebba77a-7fdc-4ca0-a1bf-7450aa871d41

Node (host MAC address) and clock (sequence number incremented whenever
the time went backwards) are left undefined (all zero) for our purpose.
