Add OSI URL dump for license

[timothystone]

Love this! I'm not a Node dev, but I use mixed tool environments, a lot. Have a great Node utility? I'll install it globally. This is one.

Yet, I often need not just the license, but I need the URL to that license for metadata.

A switch like --link or --url (no short version, -l, -u and others are already taken). Output the OSI location, e.g., https://opensource.org/license/mit. Then I could do something like: lice --url | pbcopy and copy the MIT URL to my clipboard for handy use in metadata. Or lice --url -l apache-2.0 | pbcopy for https://opensource.org/license/apache-2-0.
