Request to Add *FIR*64f_64fc Functions to IPP

The coefficients of many common FIR filters are real-only. IPP currently provides *FIR*32f_32fc functions to improve the performance of FIR filters with real-only coefficients. It would be helpful if IPP also provided corresponding *FIR*64f_64fc functions to improve the performance of FIR filters with real-only coefficients when 64-bit floating point values are required.

Thank you for considering this.
