[FEATURE SUGGESTION] Add TypeScript

[ctrlmaniac]

Hello,
i'm trying to use convert2xkt with typescript but im facing some issues. When I try to import the convert2xkt function it says that convert2xkt is not a function... do you know how to use it with typescript?

import convert2xkt from "@xeokit/xeokit-convert/dist/convert2xkt.cjs.js";

convert.convert2xkt({
      source: source,
      outputXKT: (buffer) => {
        writeFileSync(dest, buffer)
      }
    }).then(() => {
      console.log("Converted.");
    }, (errMsg) => {
        console.error("Conversion failed: " + errMsg)
    });

Hi, we haven't implemented TypeScript support for convert2xkt, but if it's a requirement we would welcome a PR to add type definitions.
