Calculation bug with scipy>1.9

[MK-2012]

Hello. In the README you say that with scipy>1.9 FVD calculations will be wrong. Could you, please, fix the calculation method for newer versions of scipy or at least elaborate further on why that happens?

updated: I haven't found an example that can reproduce the error. If you find this, please tell me. Thank you.

I haven't studied it before. This may take longer to study, so please wait. This issue will remain open until I resolve it.

Could you list the details of the runtime error you have counted?
