base64 decoding

Hey! This is super cool! Would it be possible to add a flag to indicate the URI is base64 encoded?

great feature request — i made this before the base64 encoding technique was popular. i think what i'd like the project to do is decode the base64 inline, that way the metadata still follows the standard output format
