Lower the test time for PegSolitaire

[Ant1ng2]

Testing PegSolitaire becomes pretty hard when it's solving a 5-width triangle under the current implementation. To visualize, comment out this line here and run pytest from the working directory.

TestServer takes a while to finish because we're solving all the puzzles, PegSolitaire taking the majority of the time.

I suggest the following options to improve PegSolitaire's testing time

• Design a new testing variant for PegSolitaire with less possible states
• Recode pegSolitaire, either by optimizing generateMoves and doMove or reimplementing PegSolitaire under a C-based extension.

(Edit: comment no longer applies): This issue doesn't really make sense, there's no PegSolitaire with 3-4 variants.
