I get `objectGUID` data from LDAP as binary data. I need to
convert `ubyte[]` data into a readable `UUID`. As far as I
understand, it is possible to do this via `toHexString()`, but I
have reached a dead end. Is there a way to make it more elegant,

the formatting messed up here. Try this code:

Nice, I didn't think this would work actually!
