Crypto API isn't detected on alternative platforms

I run across this using Cloudflare Workers. It should be possible to use this library by instead checking for a crypto global instead of trying to detect `window. Documentation from Cloudflare here: https://developers.cloudflare.com/workers/reference/apis/web-crypto/.

Hey, if anyone else finds this issue like I did and is using cloudflare workers, here’s what worked for me:

import {monotonicFactory} from 'ulid'
// or import {factory} from 'ulid'

const prng = () => {
  const buffer = new Uint8Array(1)
  crypto.getRandomValues(buffer)
  return buffer[0] / 0xff
}
export const ulid = monotonicFactory(prng) // or factory(prng)

This will bypass the code that checks for browser crypto and allow you to set your own. The PRNG function is the same as used internally with a different global reference.

I think this package may be abandoned, I’m working on potentially forking it.

I also could not use ulid in Web Worker of Chrome or Safari by the same reason.
