Implement cumulative sky-matrix based on sun positions and higher resolution skies. #135

Implement a better, localized version of gencumulative sky.

(Based on discussion with @mostaphaRoudsari on June 02, 2017).

We currently can do this using the SunMatrix and daylight coefficient based recipe. The challenge is with the image-based cumulative radiation which with this approach will take very long. @sariths suggested we implement a cal file to be able to use rpict for this case.

@sariths and @mostaphaRoudsari , I am just confirming that this would be VERY helpful. Having to run the equivalent of an annual study to get solar radiation right now means that I cannot do most of the solar radiation studies that I run on the legacy version without waiting a much longer time. Also, I have recently implemented an ASHRAE clear sky model in the legacy version (used for design day calculations and HVAC sizing). I will add this sky recipe to HB+ if we get this implemented. -Chris

I'm changing this to critical which actually means highly popular! Multiple users have asked me about this feature in honeybee[+].

Here is a quick test to create a cumulative sky from radiance skymtx output
