updated vapory for python under windows and made a bugfix for 16 bit images

[eelcovv]

Hi Zulko, First of all, many thanks for this python api for pov-ray, it is exactly what I was looking for! I installed it last week and started working with it. I am working with python3 under windows and fixed some errors which were related to differences between python under linux and windows. In the windows version, piping is not allowed so in order to return the image inmediately to a numpy array you have to a temporary write it to file. So I have added that. Also the name of the povray executatble is different (not povray, but pvengine64.exe). Finally I added a bug fix for 16 bit images. In order to set the byte order, it should be >u2 en not >uint16. this later may be a typical python3 change so you may want to check that. Anyway, in case you are interested to merge my changes, please go ahead. Regards
