Porter Readme Update

[Headtatt]

I assumed there had to be a way to do this, looked at Porter, looked at readme, looked at a few other addons, and was getting ready to throw up my hands in despair that the command/functionality to report things I could store but currently wasn't storing didn't exist already.

On a whim I searched history in the windower discord and found someone recently telling Kale the syntax for the command that does precisely this! Can someone please take 3 seconds and add the Porter Find command and explanation to the readme file (and while you're at it any other commands/functionalities that have somehow also been left secret?

The find command is in the readme, albeit it doesn't state what it does. FYI there are no other hidden Porter commands.

I'd recommend creating a PR that explains it.
