[yul-phaser] Tweak default values according to experiment results

Browse Source 
- Long chromosomes in the intial population are better. Set minimum and maximum to 100.
- The classic algorithm does not work well without elite. 50% performed better but I think it might be too large. Let's set it to 25%.
- Switch to uniform crossover since this is what was used in most experiments and performed well.
