Integration of more feature detectors for higher modularity

[AlbertoRemus]

Is your feature request related to a problem? Please describe.
Considering how fast computer vision is changing it could be useful to integrate various features detectors, for instance neural features

Describe the solution you'd like
It would be nice to have a sort of agnostic structure where features can be detected and matched, so that the pipeline could improve overtime

Describe alternatives you've considered
I've considered to do in a custom way, but if you have any suggestion in this direction it is more then welcome
