PackageDiscoveryError: Multiple top-level packages discovered in a flat-layout: 
['locales', 'cve_bin_tool', 'presentation'].

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.

If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:

1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names

To find more information, look for "package discovery" on setuptools docs.

I'm not sure why it's started doing this now since we've had the layout for a while, but since "locales" and "presentation" are both not actually packages, we need to either move them or update the config as directed.

I believe this is a breaking change in setuptools v61 (the first bullet point in the Breaking Changes list).
