opencv-python missing bindings for setting videocapture open timeout and read timeout

[ribeirompl-soldersmith]

cv2.VideoCapture and the .read() method can hang indefinitely in certain situations when an RTSP stream drops connection abnormally.
There appears to have been some timeout parameters added to account for this: opencv/opencv#20541
But these parameters don't appear to be available in the latest version of opencv-python.

Although, the timeout feature in general seems to be missing? It was added to opencv here opencv/opencv#6053 with a default of 30sec, but it does not seem to be functional in opencv-python. With some minimal testing, it appears to timeout (stop blocking) after around 90 seconds.

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python

Looks like the issue has been fixed in upstream repository. Both CAP_PROP_OPEN_TIMEOUT_MSEC and CAP_PROP_READ_TIMEOUT_MSEC are available in manual build with 4.8.0 and CI produced packages, e.g. https://github.com/opencv/opencv-python/actions/runs/5414007554?pr=864:

>>> q = cv.CAP_PROP_OPEN_TIMEOUT_MSEC
>>> print(q)
53
>>> print(cv.CAP_PROP_READ_TIMEOUT_MSEC)
54
