Migrate Model from dlib models to Deepface

Could we migrate the model from the dlib models to Deep face? It is more up-to-date and could potentially improve the accuracy of the detection? There could be an option to switch from one to another if there are resources or other contraints.

I could help with the migration and testing if you need it.

No files, tests, or entry points are named. Start by locating the existing dlib model integration and assessing how DeepFace could replace it or coexist as a selectable option. Done means the migration is tested and users can switch models when resource constraints require it.
