Is the default export nested / double-wrapped?

Thanks for the great module! I use it all the time in my commonJS projects and I'm hitting trouble with ESM/Typescript:

not working

import DAGMap from 'dag-map'
const map = new DAGMap()

const map = new DAGMap();
            ^
TypeError: DAGMap is not a constructor

working

import _DAGMap from 'dag-map'

// @ts-ignore
const DAGMap = _DAGMap.default

const map = new DAGMap()

I noticed that the default class exported is actually named DAG but I don't think that's related.

It seems like the UMD module is double wrapped. I'm out of my element with ESM/Typescript build processes as this is my first attempt from scratch. I'll try to circle back and see if upgrading the devDependencies/config makes the output not nested.
