Add a mode to create videos with both clips and images

[Ckrielle]

As it is right now faminator can make videos with just videos or just images. I want it to have the capability to create a video out of both smaller clips and images.

From what I had researched there is not any way you can do that in moviepy. A workaround I though about was to start concatenating videos from the file. When faminator finds an image, then it will start concatenating those images, and make a video out of them. Once that video is created, it will be added to the original video. If you happen to find something native to moviepy, or a more efficient way in general, feel free to go with that.

Be careful to not forget that you will need to change the rest of the program as well. Change the modes in argparse, and the files.txt format. I'm thinking maybe a string in the beginning of every line, either img or vid, to have the program read them in a particular way. Either that, or you can split them into two sections, e.g. first images then videos, and then do some radix sort. For that you might need to generate the time durations of the videos.

Maybe you could start from the documentation first https://zulko.github.io/moviepy/
