Camera Promises and Futures

[ClayJay3]

• All cameras will now use future for some methods where fast and parallelized copying is critical.
• Camera Examples have been cleaned up.
• Camera method names have been renamed to be more accurate.

To retrieve a copy of a frame or piece of data from the camera:

• Locally create the data type you will be retrieving
• Call the camera's request method pertaining to the data you want to get a copy of
• Call the get() of the returned std::future. This will be true or false depending on if the copy was successful.
• The data type you locally created now contains the data you requested and can be used normally.
• The same data type can be reused on the next iteration. You do not have to create a new variable every iteration.

Example use:

// Get reference to camera.
BasicCam* TestCamera1 = g_pCameraHandler->GetBasicCam(CameraHandlerThread::eHeadLeftArucoEye);
// Declare mats to store images in.
cv::Mat cvNormalFrame1;

// Loop forever.
while (true)
{
    // Grab normal frame from camera.
    std::future<bool> fuCopyStatus1 = TestCamera1->RequestFrameCopy(cvNormalFrame1);

    // Wait for copy to complete and check if it was successful.
    if(fuCopyStatus1.get())
    {
        // Display frame.
        cv::imshow("BasicCamExample Frame1", cvNormalFrame1);
    }
}

Other Changes

.clang-format has been changed to break up long string literals if they exceed the 170 character mark.
