Describe the solution you’d like

Increase/Decrease Neat.popsize after Neat.import()

Additional context

Example Code

let pop = new Neat(3, 2);
pop.import(population);

let index = new_size - population.length - 1;
while(index < new_size) {
  pop.population.push(pop.getOffspring());
  index++;
}

This is the code I used to get it working.

let index = PLAYER_AMOUNT - neat.population.length;
neat.popsize = PLAYER_AMOUNT;
if (index < 0) {
    //Reduce population
    neat.population.length = PLAYER_AMOUNT;
} else {
    while (index-- > 0) {
        neat.population.push(neat.getOffspring());
    }
}
