         MB-25339: Upgrade to snappy 1.1.6
      		 
         
         Updates manifest to download snappy 1.1.6 and corresponding build of
      		 
         python-snappy on all Unix platforms. Building python-snappy on Windows
      		 
         is virtually impossible as we are still on Python 2.7, and the MSVC
      		 
         support for that version of Python is nearly a decade out of date and
      		 
         only functions on MSVC 2008 which is EOL.
