Summary:
Summary : 1. Add two arguments --compression_level_from and --compression_level_to to check
the compression size with different compression level in the given range. Users must
specify one compression type else it will error out. Both from and to levels must
also be specified together.
2. Display the time taken to compress each file with different compressions by default.
