Feature: `impl LongRefFromWasmAbi for T where T: Tsify + FromWasmAbi` to use reference as input of async function

[Pantamis]

Currently we cannot use a reference to a tsify(from_wasm_abi) type in a async function.

This is because reference in async function needs to implement LongRefFromWasmAbi for reasons described in wasm-bindgen#3188 and here

#32 actually showed that the implementation of RefFromWasmAbi before the fix #33 was the correct one for LongRefFromWasmAbi

I plan to do a PR to implement this. This would make values deriving from_wasm_abi universally admissible as input by value or reference of a wasm-bindgen function async or not !

I am working on finding a good test for it and maybe change the documentation to feature all the nice things tsify-next provides 😁
