Research and implement xcframework embedding on iOS

[c0mtru1se]

The library can support either:

• [x] Usage of xcframework
• [ ] Usage of fat framework
• [ ] The need for a Pod distribution

Deps:

• [x] Research the need for manual linkage of native SDK dependant libs (e.g. CoreGraphics, Foundation etc.)

This is a high priority task as it would require (especially the Pod option) a large coordination with the iOS SDK team.
