ROOT::Fit::FillData only honoured the first range interval of each coordinate and warned that "support only one range interval" for any further one. Fitting a single function over several disjoint regions (e.g. a background with the peak region excluded) was therefore not possible. Collect the bins by looping over every combination of the per-coordinate ranges. A coordinate without any range contributes a single iteration spanning the full axis, so the behaviour without ranges is unchanged. DataRange::CleanRangeSet() now also merges partially overlapping ranges instead of only dropping fully contained ones, so that AddRange() keeps the range set a collection of disjoint intervals. It takes xmin and xmax by reference to widen them to the merged interval. Adds unit tests for the overlapping-range handling in DataRange and for the range handling of FillData itself.
