go.mod: github.com/google/uuid v1.2.0

full diff: https://github.com/google/uuid/compare/v1.1.2...v1.2.0

I did not switch to us the `uuid.NewString()` function; we are not currently using
`uuid.New()`, probably because it can `panic` in case an invalid UUID is produced;
in stead we are using `uuid.NewRandom()`, which is equivalent, but returns an
error instead.

Changes:

- v1.2.0: Add NewString()
  This release introduces the NewString() function which is the equivalent of
  uuid.New().String().
- v1.1.5: Syntactic cleanup
  There are no code changes. A missing period was add to a godoc comment and the
  linter was told to not complain that the results of hash.Write() are ignored
  (the function cannot fail)
- v1.1.4: Further error optimizations
  Do not allocate memory for errors (it is only one word)
- v1.1.3: Optimize error reporting
  Optimize length of time it takes to discover an input is bad by no longer using
  fmt.Errorf, which is quite slow. It now uses a custom error type that formats
  the string when the Error method is called rather than when generating the error.
