TypeError: ... is not a constructor when bundling with webpack 5

Nobody has claimed this yet.

I am not sure if this is an error with `typescript-collections` but since I upgraded to webpack 5 this package is the only one that has issues and I wonder what's the problem here. It worked back then with webpack 4.

Consider the following code, which I also pushed to https://github.com/blu3r4y/typescript-collections-webpack so that you can directly check it out and investigate the issue.

**`src/main.ts`**
```typescript
import * as Collections from 'typescript-collections';

// the next line will produce an error
let foo: Collections.Set = new Collections.Set();
foo.add("element");
console.log(foo);
```

**`tsconfig.json`**
```json
{
"compilerOptions": {
"target": "es6",
"moduleResolution": "node",
"esModuleInterop": true,
"strict": true,
}
}
```

**`webpack.config.js`**
```javascript
module.exports = {
target: "node",
entry: "./src/main.ts",
module: {
rules: [
{
test: /\.tsx?$/,
use: "ts-loader",
exclude: /node_modules/,
},
],
},
};
```

As long as I have `target: "node"` in webpack, which I need for other reasons, I get the following error. I assume that this has something to do with the way this package is importing modules (see https://stackoverflow.com/questions/40294870/module-exports-vs-export-default-in-node-js-and-es6). However, I have to admit that I am rather clueless about these internals and I still don't understand if my `tsconfig.json` or `webpack.config.js` is wrong, or this package requires a different importing strategy?

Could you help me resolve getting to run `typescript-collections` with the above configuration, while still using `target: "node"`?

Reproduce the failure using src/main.ts, tsconfig.json, and webpack.config.js from the report or the linked reproduction repository. Start by bundling with webpack 5 while keeping target: "node", then run dist/main.js and inspect the generated module handling around the reported constructor error. Done means the example runs successfully with that target and configuration.
