Niels Lohmann 6b6cc84eb6 Docs: clarify file reading speed, scope of file replacement, cross-device rename

- The 10 to 20 % figure compares parsing from a std::ifstream with reading
  the file into a string with one read() and parsing that; reading with
  istreambuf_iterator is about twice as slow as parsing from the stream.
- Say that replacing a file is general C++ advice, not library behaviour.
- std::filesystem::rename fails across file systems (EXDEV) instead of
  falling back to a copy.
