[hpsdr] Calculating engine

[Shirley Márquez Dúlcey]

NVidia's CUDA, their API and libraries for using one or more GPUs as
computing resourcese, was first released in 2007. That gaming computer
from 2009 is likely to be capable of using it. On the other hand, the
amount of computing it can do per watt won't measure up to more modern
cards, especially the upcoming GTX1070  and 1080.

Still, if the price is right...
