MiniZinc Python 0.2.2

Added

• Add output property to CLIInstance to expose the output interface given by
  MiniZinc.

Changed

• Improved interaction with solution checker models. Solution checkers can
  now be added to an ```Instance/Model`` and an ``check`` method will be
  added to the generated solution objects.
• Change the Python packaging system back to setuptools due to the excessive
  required dependencies of Poetry.

Fixed

• Fix the MiniZinc output parsing of sets of an enumerated type.
• Fix the TypeError that occurred when a hard timeout occurred.
• Allow trailing commas for sets and arrays in DZN files.
