Multi-Value Return Types

[theduke]

wasm3 seems to support multi-value, but Module::find_function only accepts WasmType return types.

Is this just a matter of updating the function signature and some glue, or is there some blocker due to the the wasm3 C api?

That might be because when this wrapper was written, multi-value return types weren't yet supported I think

Alright, I'll look into opening a PR.

Seems like the only bigger task is updating the macros.
