* Add API to statically assert signature of a `Func` This commit add a family of APIs to `Func` named `getN` where `N` is the number of arguments. Each function will attempt to statically assert the signature of a `Func` and, if matching, returns a corresponding closure which can be used to invoke the underlying function. The purpose of this commit is to add a highly optimized way to enter a wasm module, performing type checks up front and avoiding all the costs of boxing and unboxing arguments within a `Val`. In general this should be much more optimized than the previous `call` API for entering a wasm module, if the signature is statically known. * rustfmt * Remove stray debugging
