System information (version)

• OpenCV => 4.5.3
• Operating System / Platform => Linux/Python3
• Compiler => GCC

Detailed description

Getting Bresenham algorithm from 3rd party sources is a poor substitute. While it's not possible to directly translate LineIterator into other languages like Python, a substitute could be provided by OpenCV such as a generator in python which indirectly allows the similar functionality

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues,
  forum.opencv.org, Stack Overflow, etc and have not found solution
• I updated to latest OpenCV version and the issue is still there
• There is reproducer code and related data files: videos, images, onnx, etc (None needed since the functionality is missing)
