simstudy 0.6.0

New features

• Added function blockExchangekMat and blockDecayMat. Users can now generate correlation matrices that can accommodate clustered observations over time where the within-cluster correlation in the same time period can be different from the within-cluster correlation across time periods.
• Updated function genCorMat to allow generation of cluster-specific correlation matrices in case one wants to induce variability in correlation across clusters.

Major fixes

• Overhauled function addCorGen to make it more flexible. It can now handle cluster-dependent data, and not just time-dependent data. In addition,
  performance has been dramatically improved.

Minor fixes

• Fixed bug in genSpline
