performance: calling python from wasm is too slow

1

as mentioned in parent performance ticket https://github.com/bytecodealliance/wasmtime-py/issues/96#issuecomment-1497336349 we have a bottleneck when python is called from inside wasm here is a [minimum reproducible example](https://stackoverflow.com/help/minimal-reproducible-example) unlike #96 which is to be...
