feat(algebraic_topology/simplicial_object): Some API for converting between simplicial and cosimplicial (#7656) This adds some code which is helpful to convert back and forth between simplicial and cosimplicial object. For augmented objects, this doesn't follow directly from the existing API in category_theory/opposite.
