[Feature Request] Add support for piping image content to jp2a

[SunPodder]

I was thinking to play a video on the terminal. I will get each frame of a video as a image and then pass it to jp2a. So first I tried to pipe a image content to it with cat image.jpg | jp2a but it doesn't work. So can you please add this functionality please?

You can add - to read an image from stdin, e.g.: cat image.jpg | jp2a -.
