inNative needs to be able to consume a source map from wasm to the source language that it was compiled from (like C++). This source map can either be provided as a separate file, or embedded as a custom section in the webassembly module. The command line utility should provide a tool for attaching source maps to a given webassembly module.

If a source map file is provided, the generated debug information must resolve two indirections - instead of simply linking back to the source .wat textual representation, it must then use the sourcemap to go from the .wat code position to the source language position and encode this value into the resulting debug information.
