uuid1_clockseq()

[nviennot]

On the following snippet: https://github.com/zyro/elixir-uuid/blob/master/lib/uuid.ex#L440-L448
It seems that the whole thing is equivalent to :crypto.rand_bytes(2) (well, the first 14 bits) since the random generator is reseeded at every call, so there is no sequencing going on. Is this a problem?

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.
