feat: Compute material variance in material mapping

[Corentin-Allaire]

This PR is in preparation to the one that will add the automatic optimisation of the material mapping.

In this PR we add the option of computing the material variance of each bin. For this, the material mapping need to be run a second time with the material map used as an input. This is control by an option and will thus not affect the performance if not turned on.

This PR also include a new material decorator that can be used as an input for the mapping, this decorator takes in input a map of ID and binning size and use it to create protomaterial for all the mapping surface (this will allow us to change the binning of the material without having to change the input json file).
