The existing code for AlgebraActionByModule used Cartesian, an operation best avoided.
This PR adds functions: ModuleAsAlgebra, IsModuleAsAlgebra, ModuleToAlgebraIsomorphism and AlgebraToModuleIsomorphism and rewrites AlgebraActionByModule.
The next step will be to rewrite XModAlgebraByModule.

XModAlgebraByModule has been rewritten and examples added to the manual - XModAlgebra X3 and its conversion to a Cat1-algebraC3.

Removed use of AlgebraHomomorphismByFunction because CI tests with stable-4.12 were failing.

Extensive changes in this PR. The main change is the revised module action, with added files module.gd, module.gi, module3.tst. What is now needed is a revision of AlgebraAction2.
