Some PyPI origins declare `sdist` archives in formats that are not supported by [swh.core.tarball.uncompress](https://forge.softwareheritage.org/source/swh-core/browse/master/swh/core/tarball.py$76-102),
for instance [.deb](https://sentry.softwareheritage.org/organizations/swh/issues/4779/events/?project=9&query=.deb&sort=freq&statsPeriod=14d), [.egg](https://sentry.softwareheritage.org/organizations/swh/issues/4779/events/?project=9&query=.egg&sort=freq&statsPeriod=14d), [.rpm](https://sentry.softwareheritage.org/organizations/swh/issues/4779/events/?project=9&query=.rpm&sort=freq&statsPeriod=14d) or [.whl](https://sentry.softwareheritage.org/organizations/swh/issues/4779/events/?project=9&query=.whl&sort=freq&statsPeriod=14d). This leads to errors when trying to load such origins and generates a lot of noise in
sentry reports.
As the content of those archives does not match standard `sdist` format (there is no `PKG-INFO` file for instance),
we should filter them out from the artifacts to process for a PyPI origin.
