Feature request: add Fusion integration to README

[rdcstout]

Hi Stefan,

I built a Fusion add-in for BumpMesh and wanted to share it with you:

https://github.com/rdcstout/BumpMeshForFusion

It lets you select a solid body in Fusion, open it directly in BumpMesh, choose the faces you want textured, and save the finished STL or 3MF.

If you think it would be useful to other Fusion users, would you consider adding a link to it in the BumpMesh README?

Thanks for making BumpMesh available.

Roger
