MacOS version build for the project and OOP kalman filters

[GiovanniRaseraF]

Hi,

I am Giovanni Rasera and I am following the course. I would like to contribute to the project by making the following improvements:

1. I have modified the filters to be KalamanFilterBase subclasses, which allows for the selection of the filter at runtime without having to recompile all the code. This makes it easier to test and use the software. You can find the code at this link: https://github.com/GiovanniRaseraF/AKFSF-Simulation-KalmanFilterSwap

2. I have also created a version of the software that can be compiled for Mac OS. This can be found at this link: https://github.com/GiovanniRaseraF/AKFSF-Simulation-KalmanFilterSwap/tree/macbuild

I hope my contribution will be accepted and that it will be a valuable addition to the project.
I am going to make a Pull Request after rewriting a better version of my code if you accept my contribution.

Please let me know
GR
