Add a method to create mass, SFR, dust, average metallicity, average age, sSFR maps to ParticleGalaxy

[WillJRoper]

To reduce the bloat I’d be tempted to modify the mass method to simply take an arbitrary property argument and have the user pass in the property to that argument.

[stephenmwilkins]

I think it's a little more complicated than that I'm afraid. For example:

• For SFR you really just want the mass map for young (t<t_SF) star particles but with different units.
• For the average quantities you want the average in the bin not the sum. Maybe this can be achieved with providing the quantity and an optional function which defaults to np.sum()?

[WillJRoper]

Good point, those specific examples will require different functionality. The optional function won't work with the implementation though, an average flag would work though. In that case each pixel's count could be accumulated and then divide the sum by those counts.

[stephenmwilkins]

why couldn't the optional function work? By default it hasnp.sum but you can e.g. give it np.median a bit like scipy.binned_statistic.
