Monotonically increasing guarantee in the same millisecond

[arjunyel]

What is the current behavior?

perry-mitchell/ulidx#14

If the current behavior is a bug, please provide the steps to reproduce

"given const [a, b, c] = [ulid(), ulid(), ulid()] c and b could sort lower than a" ulid/javascript#74

What is the expected behavior?

Monotonically increasing guarantee in the same millisecond

What is the motivation / use case for changing the behavior?

@arjunyel
there is already a monotonic factory for it:

@yujiosaka yes but that factory doesn't provide guarantees in the same millisecond. If this library fixed that it would be a great reason to use it over the JavaScript library

@arjunyel
you mean you want the non-monotonic factory to support the monotonic behavior?

[yujiosaka]

the monotonic factory increments the least significant bit for the same milliseconds, and is tested here:
