Is there a way to include debug info?

[alexcasalboni]

When the .wasm file raises an error, the resulting backtrace does not contain any reference to the original source files (even using wasmtime::WasmBacktraceDetails::Enable).

With Rust and Go components it's possible to use compile-time flags such as --release or -no-debug to control whether debug info is included or not in the .wasm file. So I was wondering if the same would be possible with componentize-py?

Here's an example of the backtrace I get on error (where the only useful reference to my component's code is line 28):

Error: Failed to call component: error while executing at wasm backtrace:
