Implement camera capture functionality

[Blindspot22]

Description:

• Set up the module to capture video from a connected camera using OpenCV.
• Ensure that the camera capture initializes correctly and retrieves frames in real-time.

Implementation Steps:

• Import the necessary OpenCV crates and modules into the Rust project.
• Use VideoCapture::new to open the default camera (ID 0) and start capturing video.
• Implement a loop that continuously captures frames from the camera and processes them.
• Test the camera capture functionality by displaying the captured frames using OpenCV’s imshow.
