Third party warnings are suppressed now as they just polluted the warning summary in pystencils.
Removing the math optimisations as they are not used in pystencils. An Issue is created to reintroduce them again in a clean way in the future
Removing the joblib workaround as joblib is a hard dependency of pystencils
Fixing SymPy 1.9 as maximum version
Removing sympy.multiply_elementwise due to https://github.com/sympy/sympy/issues/22353. A workaround with NumPy is introduced which seems to be way more robust because NumPy has a more static API
Introducing more extra requires, which are needed to have all features of pystencils
Minor cleanup of some test cases and the datahandling
