Population numbers deviate from setting #71

It seems like the population size at times varies between 144 and 156 during each run. It should always reflect the population size setting.

Disabling interspecies mating does not a difference. I would assume it is because of this rounding:

offspring = round((average_species_fitness/total_average_species_fitness) * self.config.population_size)
species.expected_offspring = offspring
