ENH: PatchParticleHistogram: add a new cloud FO

Summary

Computes a histogram for the distribution of particle diameters and corresponding number of particles hitting on a given list of patches.

A minimal example by using constant/reactingCloud1Properties.cloudFunctions:

patchParticleHistogram1
{
    // Mandatory entries (unmodifiable)
    type             patchParticleHistogram;
    patches          (<patch1> <patch2> ... <patchN>);
    nBins            10;
    min              0.1;
    max              10.0;
    maxStoredParcels 20;
}

Risks

No change to user inputs / no risk to regression.
