Context-Adaptive Interpolator (CAI)

While being nearest to actual PRNU thanks to CAI, it does not seem to help:

RMS diff with average image = 100.26988483431852
RMS diff with average CAI images = 79.12339215595037

Context-Adaptive Interpolator (CAI) 
RMS diff with average image = 141.44015650123464
RMS diff with CAI images = 103.2666640411378

seems to show promising results.

Now that have possibly a first version, should try to compare with other models to see if it works.
