Description: # nv21
        Functions for reading and decoding the data of frames in NV21 format.
        
        Basically it wraps the cv2-based conversion with some check in order to avoid some confusing cv2 errors.
        
        ## Available functions
        
        * `nv21_to_rgb`
        * `read_nv21_from_file`
        * `yuv_to_nv21`
        
        Example
        ```python
        import cv2
        import matplotlib.pyplot as plt  # do not forget to install `matplotlib` first
        
        import nv21
        
        
        # Check the "data" folder of this repository.
        img = cv2.imread('./data/example.png')[..., ::-1]  # to RGB
        h, w = img.shape[:2]
        
        nv21_data = nv21.yuv_to_nv21(
            cv2.cvtColor(img, cv2.COLOR_RGB2YUV)
        )
        
        restored_img = nv21.nv21_to_rgb(nv21_data, w, h)
        
        # Draw results
        plt.subplot(1, 3, 1)
        plt.axis('off')
        plt.imshow(img)
        
        plt.subplot(1, 3, 2)
        plt.axis('off')
        plt.imshow(nv21_data, cmap='gray')
        
        plt.subplot(1, 3, 3)
        plt.axis('off')
        plt.imshow(restored_img)
        
        plt.show()
        ```
