Update to support latest ECMAScript

[nickjfrench]

I've been looking for a good loot table to implement into a Discord bot, and so far this seems like the best option. But I can see this was last updated 3 years ago and doesn't support the latest changes in ECMAScript. E.g. Replace "var" with let and const.

Is there any plans for a future update? Would love to be able to use this without any possible issues.

hey @nickjfrench I maintain the npm package for this. I'd like an es module too and some modernization.

I'll put a PR together for this.
