Opty Versions Save

• Dropped support for Python 2.7, 3.6, & 3.7.
• Added support for Python 3.9, 3.10, & 3.11.
• Bumped minimum dependencies up to versions released around mid 2020, except for cyipopt which is set to 1.1.0 since that is the first version released on PyPi under the name cyipopt (instead of ipopt).
• Much faster symbolic Jacobian algorithm introduced. For constraints made up of hundreds of thousands SymPy operations there can be greater than 200X performance increase.
• logging.info() used for providing information to the user.
• Moved to Github Actions continous integration.
