Modernize std::sort with ranges and projections

In PPCTables.cpp, the code is currently unused so I was unable to test it.

In CustomPipeline.cpp, a pointer to member function cannot be used due to 16.4.5.2.1 of the C++ Standard regarding "addressable functions". https://eel.is/c++draft/namespace.std#6

In Fs.cpp and DirectoryBlob.cpp, these examples used projections in a previous iteration of this commit, but no longer do. Still, they remain in this commit because the PR they would actually belong to is already merged.
