Hi, is there an option to swap the SWC internal with wasm version instead of the default node addon?

Something like

import { rollup } from "npm:rollup"
import { swc } from "npm:rollup-plugin-swc3"

const build = await rollup({
  input: ["main.ts", "lib.mts"],
  plugins: [
    swc({
      wasm: "https://esm.sh/@swc/wasm-web/wasm_bg.wasm"
    }),
  ],
})
await build.write({ dir: "dist", format: "es" })

Error: Failed to convert napi value into rust type `Option<T>`

I am still figuring out how to fallback from @swc/core to @swc/wasm.

Generally, I'd prefer @swc/core whenever possible. @swc/core is significantly faster than @swc/wasm.

I've done some experiment to integrate @swc/wasm with es-module-shims in the past. Hope that can help.

There is a hack: map @swc/core to @swc/wasm in deno's import map.
