Add LINQPad NuGet samples

[sblom]

Looks like we've resolved the long-standing "please provide usage examples" request by making the README much better, but I have been intending for ages to add LINQPad samples to the NuGet package so that a developer that wants to kick the tires can simply add the NuGet package to a LINQPad query and start playing around.

Any objections before I roll up my sleeves on that project?

I don't use LINQPad myself, so I don't really have any basis to judge this upon. But more documentation can't hurt, so I give it a 👍!

yeah note that there's also now https://github.com/linked-data-dotnet/json-ld.net-Demo which helps somewhat
