Ensure iOS Implementation does not break anything

[Johnnyg63]

This issue is been used to track the progess of the iOS implementation.
Currently the iOS is in Aphla/Beta testing with a few of our Mac Guru's in the betatesters group.

If you would like a copy of the olcPixelGameEngine3.h with iOS reach out to us on discord.

Creating a new branch for this, do not have the patience to fix all the conflicts
