Description

I need to preselect rectangle on the frame, and i can't find function selectROI(). This function exists in C++ and Python libs.

frame.selectROI() and cv.selectROI(frame) not working.

If there is exists same function, plz, tell me.

Contributor guide

Research direction
Add a binding for cv::selectROI() following the existing pattern in opencv4nodejs, implementing the function in C++ and exposing it to JavaScript.
