[Difficulty Calculation] StrainSolverData not cleared when computing the 2nd round (right-hand favored difficulty )for 7k

[WilliamQiufeng]

Quaver.API/Quaver.API/Maps/Processors/Difficulty/Rulesets/Keys/DifficultyProcessorKeys.cs

Line 153 in 31f2847

OverallDifficulty = (ComputeForOverallDifficulty(rate, Hand.Left) + ComputeForOverallDifficulty(rate, Hand.Right) ) / 2;

In the second ComputeForOverallDifficulty call, StrainSolverData is not cleared when it's supposed to in

Quaver.API/Quaver.API/Maps/Processors/Difficulty/Rulesets/Keys/DifficultyProcessorKeys.cs

Line 184 in d766e81

private void ComputeBaseStrainStates(float rate, Hand assumeHand)

This causes an issue where, during the calculation for right-hand favored 7k difficulty rating, the left-hand favored patterns would also be considered.
