Bulk delete packages from your GitHub registry

Hello folks.

Thought I'd share a small script I wrote for this annoying Github registry issue to delete container type packages.

The problem I found if your package has `/` in it it wouldn't find it using the REST api. So we need to escape that using %2F. That works and the script does this for you.

Anyways, I linked the gist that contains the script. It could be further enhanced to work for Organizations or other types like docker npm, etc.
