Subject: [PATCH] Remove `__cpp_lib_filesystem` check for `<filesystem>`

This project has long since targetted `c++17`, which includes `<filesystem>` as part of the standard. It has then been updated to target `c++20`. Further the `__cpp_lib_filesystem` macro is defined in `<version>` which is part of the `c++20` standard. That means we'd need to use a `c++20` feature to detect support for a `c++17` feature. Seems kind of pointless.
