Bug - id length varies randomly toggles between 14 and 15.

[Sulaiman90]

When I tested in nodejs and npm testkit in https://npm.runkit.com/uniqid, id length switches between 14 & 15.
Its is not constant.

and for me it is 16 and not 18 based on the document.

Same I'm getting 14 bytes long instead of 18 as documented.
Looks like the documentation is bad because the way it's done in the source mac can have varying number of digits, and pid as well, so one can't infer a constant length for the uniqid.

same, we get 15 char long (expecting 16)

I've been getting 9 but it's probably because my code is running in a Firebase cloud function.
