This commit leverages two new attributes in the Rust compiler, `#[wasm_custom_section]` and `#[wasm_import_module]`. These two attributes allow removing a lot of hacks found in wasm-bindgen and also allows removing the requirement of `wasm-opt` to remove the unused data sections. This does require two new nightly features but we already required the `proc_macro` nightly feature and these will hopefully be stabilized before that feature!
