Dear Bernd, Thank you for this interesting contribution. I use these sorts of filters frequently so I will be interested to give it a look. I just build my Butterworths in k space so I will be interested to see how yours work differently.
The math package is in flux as others can tell you, however I think such functionality fits the commons mission quite well and I am certainly happy to help support the code to give it a home here some how.
