crypto: add `randomULID` function
I propose to land randomULID
in the crypto
subsystem.
ULID are lexicographically sortable identifiers contaning both the time it was generated and a random part. Spec can be found here: https://github.com/ulid/spec
ULID implementation exists in userland, currently getting around 768'000 downloads per week: https://www.npmjs.com/package/ulid Since its release, popularity constantly grew: https://npmtrends.com/ulid
I will be happy to get feedbacks on the implementation and I'm obviously open to discuss if you have reluctance to land it in Node.js.
