Cannot import module SFM

[acalatayud]

Expected behaviour

SFM module and functions should be usable with python due to being included in the contrib package.

Actual behaviour

When i install the contrib package i can not import the module cv2.sfm.

Steps to reproduce

• opencv-contrib-python version: 4.2.0.32

SFM module has long list of non-standard dependencies like glog, gflags, ceres, etc. That's why it's not included into regular binary distribution. The only way to enable the module is build OpenCV-Python package manually.
