processed The Whale

Processed the LRGB data for The Whale galaxy aka NGC 4631.

Used the data from 14 Dec '17.

Again, I used GraXpert on the original FITS files to flatten the gradients. Used the Kriging interpolation method this time, with manually placed sample points.

And, like before, this made the post-processing work easier.
