Description

Hi, after updating to v0.91.0, my import of CyClpSimplex no longer works it give me the error "AttributeError: type object 'cylp.cy.CyClpSimplex.CyClpSimplex' has no attribute '__reduce_cython__' ". Also, before updating to v0.91.0, I was receiving segfault errors when trying to use CyClpSimplex().addVariables() and CyClpSimplex().addConstraints(). The same problem occurred when trying to use CyClpSimplex().CLP_addVariable() and CyClpSimplex().CLP_addConstraint().
