Difficult implement fast vector interpolation on this CPU:
NanoVNA measure real imag, for convert it to Z angle need:
Z = sqrtf(real*real + imag * imag)
angle = atan(real, imag); // here more difficults, need get correct sign
After interpolation need back to real imag, also need prevent change angle
from 360 degree to 0, lot of mathematic for this small device (H and V2 not
have hardware FPU, so any float calculations emulated, slow) ?
Linear interpolation work good, but need know this limits
