uuid1_clockseq() about elixir-uuid

[zyro]

From section 4.1.5. of the RFC:

If the previous value of the clock sequence is known, it can just be incremented; otherwise it should be set to a random or high-quality pseudo-random value.

So a random clock sequence is OK. Alternatively UUID.uuid1/3 takes a clock sequence and node values, so the application can choose to track the previous ones if this is needed.

In that case, uuid1_clockseq() can be implemented with just a call to rand_bytes(2) ? Otherwise, the code seems a bit deceptive.
