Write IPC stream directly to a Uint8Array rather than a vector?

Is it not possible to write the IPC stream directly to a Uint8Array rather than a vector? Not super familiar with rust/wasm at all but was going to look into this tomorrow. Just wanted to check if there was some reason you hadn't first.

The current implementation was done because it seemed to work reliably. I think in general it's not possible to write the IPC stream directly into a Uint8Array because the Uint8Array is memory managed by JS (outside WASM) while the Vec<u8> is memory managed by Rust (inside WASM).

It's possible this could be improved with reference types, see #69 and https://rustwasm.github.io/wasm-bindgen/reference/reference-types.html
