Can implement a dedicated issue for the mean denoiser support for attributing source camera.

Example for a given pixel: RAISE: -1 Rafael: 1 Noise: 0.1 RMS: Rafael Correlation: -0.1 according to signal.correlate2d

>>> signal.correlate2d([[1]], [[0.1]])
array([[0.1]])

…
Implement correlation

Allowing using correct camera training set mean seems fine as it is quite easy to check what scene, hence dataset it is in the case of flat-field images.

Well as quite expected:

Note that if Denoiser.MEAN works fine, later on or even right now we will be interested in not using it as it requires identical scene images.
