findHomography is missing an overload and USAC methods are missing.

[JoanCharmant]

Hi,

It seems the following overload to findHomography is missing:

Mat cv::findHomography (InputArray srcPoints, InputArray dstPoints, OutputArray mask, const UsacParams &params)

Declaration.

It makes use of the cv::UsacParams structure which is also not wrapped as far as I can tell.

Furthermore, the HomographyMethods enum passed to the existing Cv2.FindHomography is missing the new USAC values.

As can be seen here in the implementation, the cv::findHomography is capable of understanding the new methods (USAC_DEFAULT, USAC_PARALLEL, USAC_FAST, etc.) so I think these should be added to the HomographyMethods enum, or it should be merged with RobustEstimationAlgorithms as I don't think there are any differences at openCV level (?).

The wrapped method is also missing the last two parameters int maxIters and double confidence which have default values at the C++ level.

Thanks!
