This will shrink the x1- and x2-grids such that the minimal and maximal values of each dimension reflect the range of non-zero subgrid values. That should also shrink the size of grids a bit (see https://github.com/NNPDF/pineappl/issues/151), however the main advantage is that one can now read off the x ranges for each subgrid, which can be helpful sometimes. Finally, the generation of EKOs should be faster since the operators have to be generated for fewer points.
