Add support for Tuples

[Fracas42]

Feature Description: It would be useful to allow support for tuples as they allow better readability than using an object array.

I'd like to just append deconstruction onto this request https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/functional/deconstruct

User defined value types don't really work in Udon at all currently. It'd just incur a massive overhead any time you attempted to use them because they'd need to fake all of the copy by value behavior and do heap allocations in the process. It's likely you'd see https://learn.microsoft.com/en-us/dotnet/api/system.tuple-2?view=net-7.0 and its other variants first.
