docs: include link to PyCafe for a live example

[maartenbreddels]

Hi Randy,

I think it would be nice if people can play directly with your library on https://py.cafe
I don't know if you like that the link to the project links to a personal project of mine.
If something needs to change, you can always fork it, edit it and point to your project.

Let me know what you think.

Regards,

Maarten

Including the markdown below so you can preview it:

Run and edit this example in Py.Cafe

Hey @maartenbreddels, thanks for the PR! Don't mind that it's in your account, though, is there any benefit to having my own account (for maintenance or anything else)?

[maartenbreddels]

Yeah, purely so you can edit it yourself. Now, if you want to make a change you can

1. ask me
2. fork it, edit and push, and update the link in your README

PS: oops, accidentally closed it :)

[maartenbreddels]

No idea why I cannot re-open this PR, do you have permissions/rights to do that?

[randyzwitch]

I'll merge this, and if it's popular enough where someone asks for an update, then we can pursue making an account for me

Thanks Randy. You can log in with your GitHub account if you need to fork and edit.
