Fix command line version

Change default to not fallback to Math.random

Breaking changes to API with new module format

We're modernizing the library, with proper ES6 exporting, and CommonJS support with rollup. As a result, the API will change.

For TypeScript and ES6 consumers

import { ulid, factory, monotonicFactory } from 'ulid'

ulid()

For CommonJS consumers Sorry guys, if you can tell me a better way, I'd be happy to implement it!

const ULID = require('ulid')

ULID.ulid()

For browser usage

<script src="/path/to/ulid.js"></script>
<script>
    ULID.ulid()
</script>

Strictly monotonic clocks

Spec'ed out and implemented! See the readme for more information

• Specify edge cases in schema
• Improved jest support
