Breaking changes

• LazySet is not restricted to convex sets anymore. This is a major breaking change if convexity was assumed. To write code with the previous restriction to convex sets, you can use ConvexSet instead. Currently there is no additional functionality for LazySet types that are not ConvexSet, but the code will be generalized from ConvexSet to LazySet step by step. Hence, over time, the ConvexSet restriction may become redundant and be removed. The long-term solution to check for convexity by type is to use the isconvextype trait. (#3022, #3023)
• Outsource auxiliary code to ReachabilityBase (#3021)

Features

• Add ConvexSet interface (#2992)
• Add rand for SparsePolynomialZonotope (#3020)

Closed issues:

• Add rand function to PZ subtypes (#2984)
