1. Put a URL on the clipboard.
2. Insert a Yubikey with CCID on. (This is why the script is called ykgodot: first it waits for a URL then it waits for a Yubikey. So much waiting.)
3. pass will be called automatically to copy the password for the domain of the URL. We use tldextract to find the domain.
4. On Linux (tested) and Mac OS X (untested) a notification will appear about the successful copying.

Optionally, install the copy url extension into Chrome.

pip can install pyperclip, retrying and tldextract. No other dependencies.
