Add ability to show more info in search and status subcommands

This feature also introduces the followiing changes
* aur-search command now works as expected with multiterms
* printer classes for managing of data print
* --sort-by argument for aur-search subcommand instead of using package
  name
* --quiet argument now has also --no-quite option
* if --quite is supplied, the log level will be set to warn instead of
  critical to be able to see error messages
* pretty_datetime function now also supports datetime objects
* BuildStatus is now pure dataclass
