update lisa c4 transitions/probabilities - #2441

1 Enemy: C4 always emits 1 Discharge per Arc i.e. 100% chance to emit 1 Discharge.

--> unchanged

2 Enemies: C4 emits either 1 or 2 Dischages per Arc.

• The first Arc has a different probability distribution:
  • 60% chance to emit 1 Discharge
  • 40% chance to emit 2 Discharges
• For all subsequent Arcs, the probabilities change to:
  • 15% chance to emit 1 Discharge
  • 85% chance to emit 2 Discharges

--> cleaner rates

3+ Enemies: C4 emits either 1, 2, or 3 Discharges per Arc.

• The first Arc will never emit 3 Discharges, instead having probabilities:
  • 55% chance to emit 1 Discharge
  • 45% chance to emit 2 Discharges
• From there, the discharge count follows a Markov chain with the following transition probabilities:

| Current Arc  | Next Arc: 1 Discharge | Next Arc: 2 Discharges| Next Arc: 3 Discharges|
|--------------|-----------------------|-----------------------|-----------------------|
| 1 Discharge  | 20%                   | 50%                   | 30%                   |
| 2 Discharges | 25%                   | 50%                   | 25%                   |
| 3 Discharges | 50%                   | 50%                   | 0%                    |

--> cleaner and more accurate rates (didnt take into account a transition way back then)
