PR: #108

  • fix PER breakage on negative error = reward by adding a bump min_priority = abs(10 * SOLVED_MEAN_REWARD)
  • add a positive min_priority for all problems since they may have negative rewards. We cannot do error = abs(reward) because it is sign sensitive for priority calculation
  • add assert guard to ensure priority is not nan
