wasi:http type conversions

Is there a recommended method to convert the WASI-http proxy world's types to those used in the greater Rust ecosystem, in the `http` crate?

Would it be suitable for such a conversion to be hosted under the `wasi` crate? (Likely under a feature flag?)

The `wasmtime-wasi-http` crate may also be of relevance here, although I haven't dug too deeply just yet.
