This MR uses FunctorImageFilter to remove classes deriving from QuaternaryFunctorImageFilter and TernaryFunctorImageFilter and replace them by template using declarations, in a similar way than in !318 (merged) .
Rationale
This removes classes definitions without changing the feature scope. Once this MR and !318 (merged), we will be able to remove QuaternaryFunctorImageFilter since no classes in OTB will depend on it anymore.
Implementation Details
Documentation
I followed the same pattern as in !318 (merged) to document the template using and link to the applied functor.
