Missed collision detection during the simulation

[parazjx]

Thanks for all the great works! The project has been a great help in verifying my theories about playing pool on daily play.

But sometimes I found the ball went through with other ball in EightBall game when i put cue ball in 1/4 place and others in 3/4 place.

First change position In pooltool/layouts.py:

def _get_eight_ball_rack:
...
blueprint = ball_cluster_blueprint(
seed=BallPos([], (0.5, 0.75), solids),
...
cue = BallPos([], (0.5, 0.25), {"cue"})

Then with the test code follow:

shot = pt.System(
    cue=pt.Cue(cue_ball_id="cue"),
    table=(table := pt.Table.default()),
    balls=pt.get_rack(
        pt.GameType.EIGHTBALL, table
    ),
)
shot.strike(V0=3.262213, phi=81.83468, theta=0, a= 0, b=0)
pt.simulate(shot, inplace=True)   
pt.show(shot)

The magic number of V0 and phi are just copied when i shot by hand.
I am not sure which step caused the problem, wether the time calculation error when solving the equation or the omission when querying the transition event.

Thanks again for all great works!
