[WIP] EAGLE - Sampled stellar evolution

Copy over a feature of the EAGLE model:

• Stars carry the time of their last enrichment.
• Stars above a certain age do enrichment only every N steps.
• Loops over stars' neighbours are not run for stars not doing enrichment.

@folkert could you check for me whether the isolated galaxy with feedback yields the same result in this branch and in master? Thanks!

Yes, I can do that.

It does not yield the exact same result, there are subtle differences, particles are at slighlty different positions causing surface density maps to be different, also the SFH is a bit different, the one on the SFH is very small <1%.

Can you try setting stellar_evolution_sampling_rate to 1 and see whether that matches master? and then maybe to 3? That second one should be in-between.

I ran both of them and stellar_evolution_sampling_rate: 1 does not seem to match the master.

Can you share the figures?
