setup.py and especially data_files are deprecated #1170
Description
********************************************************************************
Please avoid running ``setup.py`` directly.
Instead, use pypa/build, pypa/installer or other
standards-based tools.
By 2025-Oct-31, you need to update your project and remove deprecated calls
or your builds will no longer be supported.
See https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html for details.
********************************************************************************
There is a workaround using pypa-build and pypa-installer, but data_files isn't supported anymore, so everything will be installed in /usr/lib/python/site-packages.
Please update to a non-deprecated build system or package maintainers will have a hard time packaging input-remapper.
