  Notes:
  
  1. This patch requires D23490 <https://phabricator.kde.org/D23490> and the following KIO patch:

  2. If I name the protocol as "7z", "Invalid protocol" error will be thrown, so I use "sevenz" instead.
  3. I am not sure whether it is needed to include `k7zip.h` in `archive/kio_archivebase.cpp`.
  4. It can take some time to load the 7z archive using this new protocol.
