Convert to Typescript

[tboulis]

Hello! I would like to see this project support typescript. I would also love to start doing it myself. Let me know if it's ok to start a PR for this

This would indeed be much appreciated.

or at least add @types/nodejs-pptx package

Hi, I forked a version in order to use nestjs

• typescript
• es6 import
  If anyone needs it, you can give it a try.

{
   "@imagine10255/pptxgents": "3.13.0-beta.7"
}

Because it was changed to vite, I am only sure that it is available in nestjs. I have not tested the browser version, so I am not sure whether it is suitable for posting PR.
