Container-based LUT generation

They are likely to be ~2x faster to instanciate and would allow code factorization

It would allow to perform LUT generation while processing the first image in a histogram like manner. This initiate a new generation of regriding engines. Let's postpone this issue to v0.15

The array builder could nevertheless be used for image distortion

For clarity it would be nice to call it "SparseContainer". The container is likely to build the structure in a format like COO (IJV) and then transform it into CSR or EEL format (LUT)

While building the array, it would be cool to generate some statistics on the number of element per line in order to optimize the execution speed during the matrix multiplication

The code is basically available but not yet widely used. Let's postpone this to 0.17 to realease 0.16 shortly
