Add event 7

[TechnologyClassroom]

Event 7 needs to match the pages 7 and 8 of the first printing in dicemechanicsim.py. The simulation plays events 1 through 6 currently and has a beta version of event 7 that did not make it into the final version. Read gamelogic.md for a quick rundown of how the game works and the differences between the beta version of event 7 and the 1.0 version of event 7.

• Bracket system that pits all runner up Player Characters (PCs) against each other to decide who faces the player with the highest madness.
• The last two players in the bracket may team up.
• Final Event 7 battle is a best 2 out of 3 with the highest madness player against the winner of the bracket.
• D12 will settle ties during event 7.
• Event 7 edge case: If 2 or more players tie for highest madness, roll off with D12. The winner of all D12 rolls has the highest madness and must be stopped by the winner of the bracket.
• Event 7 edge case: What happens when two players tie for highest madness and reputation?
