Ability to unpack in a flat directory to prevent too long file paths

Thanks for a handy tool!

Sometimes the resulting paths are too long to fit into directories or subdirectories. Would it be possible to have a flag that "flattens" the output, and just puts everything into one directory? I understand this would break local references, so it should be optional.

Thanks!

Start by locating the CLI option parsing and the extraction path-building logic in the TypeScript project. Trace how output paths and local references are handled, then define the optional flat-output behavior and verify it with the existing extraction tests or fixtures.
