Error using wasm2wat on a wasm file generated by Moonbit: "unexpected type form (got -0x30)"

[panicfrog]

I encountered an error message when attempting to use the wasm2wat tool to convert a .wasm file generated by the Moonbit toolchain with --target wasm-gc into the .wat format. The error message indicated an unexpected type form. Here are the wasm file. i also generated a .wat format wat file by moonbit.

• wasm2wat version: 1.0.34
• Operating System: Macos Ventura 13.5.2 x86_64
• Moonbit version: moon 0.1.0 (9e06fe3 2024-02-05)

WABT does not support the GC (or function-references) proposals; we don't even have a line for them in our feature matrix in the README yet. You best bet is probably to use wasm-tools parse (https://github.com/bytecodealliance/wasm-tools/) instead.
