Design and Implement a `Concatenate` Interface

[Pedrexus]

The library currently lacks an intuitive method to concatenate or join multiple videos. A new interface, concatenate, needs to be designed and implemented to provide this functionality. Additionally, to make the operation more Pythonic and user-friendly, we should support the use of the __add__ magic method.

Proposed Interface:

1. Concatenate Method:

def concatenate(videos: List[Video]) -> Video:
    """
    Concatenate multiple video objects in the order they appear in the list.

    Args:
    - videos (List[Video]): A list of video objects to be concatenated.

    Returns:
    - Video: A new video object that represents the concatenated videos.
    """

Usage Example:

concatenated_video = Video.concatenate([video1, video2, video3])

2. Overload __add__ method:

The __add__ method should be implemented in the Video class to allow the use of the + operator for concatenating videos.

Usage Example:

concatenated_video = video1 + video2 + video3

Expected Outcome:

• Users should be able to easily concatenate multiple video objects using the proposed concatenate method.
• The + operator should concatenate video objects seamlessly, offering an intuitive and Pythonic way to join videos.

Additional Notes:

• We need to ensure videos have the same resolution, frame rate, and other properties or decide how to handle discrepancies.
• It would be good to add error handling for mismatched video properties or provide options to automatically adjust them.
• We can do validation with the pydantic library.
