Write a function that takes a space of agents and tests which are ESS.

Not sure how to do this other than agent sims, but this has arbitrary parameters. Something ESS in low pop is definitely ESS in high pop, but the converse is not true. I could run it for, say 10k generations with a population of like 20 where every agent but one starts with pop=1.

ESS has a pretty specific mathematical definition and can be computed from the payoff matrix. Its basically just the statement cannot be invaded i.e., any mutation is more than 50% likely to be wiped out.
