could you add support for basic fast sin-cos function set to speed-up math calc (DSP-88) #57

INSTRUCTIONS

The default sin-cos functions will cause math iterate compute, which is so slow and unsuitable for a MCU, many platform use lookup table and IQmath format to speed-up those math functions on MCU, especially MCUs without FPU.

Hi @wanckl

Yes, we will add them soon.

Thank you for idea.

Thank you very much! Dmitry
