Intl not working

Intl doesn't seem to work. I think we are missing icudtl.dat that needs to be included somehow. 

This code

```JavaScript
console.log(new Intl.Collator('en').compare('hello', 'hello'))
```

throws an error

```shell
Unhandled Rejection
RangeError: Internal error. Icu error.
    at new Collator (<anonymous>)
    at techempower.mjs:101:13
process will exit
```
