Mac (arm64) support

[daadu]

Hey,

I came across declaraCAD on the OCCT websites registry, and wanted to give it a try.

I realised the release doesn't inclure a pre-built artifact for macos.

I tried to build from source based on the docs, but realised that it is using a pyocct fork, publishing to it's conda channel. This channel also doesn't include macos builts.

Following are my queries related to it:

1. Is the upstream pyOCCT API compatible, or does DeclaraCAD depend on changes in your fork?
2. Is there a macos support planned? If you can share some pointers, I would be happy to work on it.

Regards.
