_7zz: correct license (#163999)
* _7zz: correct license and remove p7zip dependency The code under Compress/Rar* is licensed under a specific unRAR license Also Compress/LzfseDecoder.cpp is covered by BSD3 The unRAR code is removed from the `.tar.xz` since the license posits you agree or remove the code from your hard drive This adds some complexity to updating 7zz so there is also an update script Meta has been updated and tweaked Source is now downloaded from sourceforge in the `.tar.xz` version to avoid depending on p7zip * _7zz: add notice of the license updates and optional unRAR licenced code
