The following PR allows fixing one of the convolutions and return a new Grid with lower dimension. For eg. it can be used to convert a SIDIS grid into DIS. The method is tested (in pineappl/tests/drell_yan_lo.rs) and works.

TODO:

  • simplify a bit the logic
  • improve the error handling and CLI interface
  • perform extensive checks (checked in DY-like and single-inclusive hadron production case)
  • propagate into the APIs
