Unwasm doesn't work with Emscripten output

[brendandahl]

Environment

Node: v19.9.0
Unwasm: 0.3.9

Reproduction

1. build hello world with emscripten
   emcc -sWASM_ESM_INTEGRATION hello.c -o hello.mjs
2. Add that hello.mjs to the rollup config and enable unwasm

Describe the bug

The binary fails to parse with
Error: Unexpected instruction: 0xfc03

The wasm-parser package is not being updated with the latest instructions. Strangely, the code exists, but the owner hasn't done a new release.
