This package contains DevTools utilities for working with source maps.

This is used in multiple contexts:

• The debugger loads this package directly when running from the launchpad in a tab by itself
• The toolbox inside Firefox loads this package and passes it down to interested tools so that they can share a common instance of the utilities

This package assumes that an application using this code will make the worker.js, and dwarf_to_json.wasm files available and call startSourceMapWorker(workerURL, wasmRoot) to initialize the worker and specify the location of the wasm asset.
