Missing DataSet constructor in Typescript definitions

[sgielen]

In issue #112, it's suggested to create a DataSet like this:

const dataSet = new dicomParser.DataSet(byteStream.byteArrayParser, byteStream.byteArray, {});

I see in dataSet.js that this is supported:

export default class DataSet {
  constructor (byteArrayParser, byteArray, elements) {
    this.byteArrayParser = byteArrayParser;
    this.byteArray = byteArray;
    this.elements = elements;
  }
// ...

However, the Typescript definition does not allow this because here, DataSet is an interface and not a class with a constructor:

  export interface DataSet {
    byteArray: ByteArray;
    byteArrayParser : ByteArrayParser;
    /**
     * Access element with the DICOM tag in the format xGGGGEEEE.
     */
    elements: {
      [tag: string]: Element;
    };
    warnings: string[];

    /* ... no constructor ... */
  }

Is there a way to do this in proper Typescript that I'm missing?
