Add option to download Gif

[jaredsburrows]

Based on your example, https://swimmingkiim.github.io/gif_maker/, how do you then download the GIf?

First, thank you for submitting this issue. I found that the example code on this repository doesn't include a function that is related to downloading GIF results. Soon, I'll make gif_maker repository into a public repository so that people can find an example code for a demo application.

Also, I'll consider adding a download function to this package.

Again, thanks a lot :)
