I don't think I wrote it as a library yet, but the idea is pretty
simple: they all start with "data:" so you look for that.
Then there's a type after that, so you read the string until the
next ; character. It will be like image/png or image/jpeg.
Then there's the semicolon and the string "base64,".
After that, the rest of the string is base64 data.
ubyte data = Base64.decode(rest_of_string);
And now that you have the data you can write it to a file:
And that should make the file you want.
