Create TikZ pictures within draw.io

• I agree to follow the Code of Conduct that this project adheres to.
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Is your feature request related to a problem? Please describe. It's cumbersome to use TikZ pictures within draw.io because:

1. I need to author the TikZ pictures in a separate program
2. I need to compile them to an image format and import them into draw.io
3. I have to save the TikZ source code separately if I want to change the TikZ pictures later.
4. If I want to update the picture, I have to go through this process again

Describe the solution you'd like I want to be able to create TikZ pictures from within draw.io, similar to LaTeX & MathJax.

Describe alternatives you've considered My current best solution is to use the online TikZ editor and download an SVG to import into draw.io. In draw.io, I put the source code next to the image so that I can change it later.
