The Tuplewise operator extends the functionality of the Pairwise operator to N-tuples.

The overload set is generated using a .tt template and is currently set to a max size of 4-tuple, but this could be set to much larger except that the unit tests use BreakingFunc.Of<>() which only has a limited set of overloads. If anyone wants a larger overload set then this is easily extended.

Thanks for this PR! It's looking good for a start. I am quite short on time these days so I'll have to review this in multiple sittings (unless others can jump in and help) but I've started with an initial one for now.

Do you know what this is and do we need it?

I believe it's because I've added the T4 template to the test project. I don't believe it's 'needed' as far as building is concerned, but I think it's basically a tag used by the IDE to expose certain things for the project.

I thought that's what the service in the following line was but seems 82a7f48d-3b50-4b1e-b82e-3ada8210c358 is for tests so this one must be for T4. I was just surprised it wasn't already there since we've been using T4 since a long time.

This means we'll need tt.sh/tt.cmd to cover the test project as well now.

Is the allocation-free a big enough of an advantage to introduce a separate operator with 3 overloads? Seems like the behavior at least is already covered by Window. Keep in mind the 2-param version is effectively the same as Lag/Lead as well.
