Sift image feature extraction python3.6 + opencv3.3 code

Some of the functions in opencv3.x are changed:

1. SIFT: can use Help (cv2.xfeatures2d) query

2.drawKeypoints: Also use the Help () method to query

Opencv3 version Sift,surf and other unstable algorithmic functions are placed in the contrib version of opencv3.x. The module https://www.lfd.uci.edu/~gohlke/pythonlibs/
