Auto copy OTP to clipboard

The tool attempts to automatically copy successfully generated code to the clipboard. It uses pyperclip module for cross-platform copying text to the clipboard.

Example:

$ otp cloud
324982

At this point, provided your system supports it, the above OTP should be in the clipboard.

Copy to clipboard issue

Pyperclip uses various mechanisms to copy text to the clipboard. If your system is missing them, you may see a debug message that says:

Pyperclip could not find a copy/paste mechanism for your system.
