Subject: [PATCH] Conditionalize wasm_bindgen to fix compile error on
 wasm32-wasi

From investigation for #115, now three targets:

- wasm32-unknown-unknown: build with `wasm-pack build`, uses
the #[wasm_bindgen] directive on main()

- wasm32-wasi: build with `cargo +nightly build --target wasm32-wasi`,
requires normal main()

- native targets: same as wasm32-wasi
