What's new and different:

• Support python3.12 and sqlacodegen3.0.0rc3 SQLAlchemy2.0.25.
• Support for generate controller layer.
• Support for generate Model layer include many model py files.
• Support for Flask-SQLAlchemy syntax using --flask option.
• Defaults to generating backrefs in relationships. --nobackref still included as option in case backrefs are not wanted.
• Naming of backrefs is class name in snake_case (as opposed to CamelCase) and is pluralized if it's Many-to-One or Many-to-Many using inflect.
• Primary joins are explicit.
• If column has a server_default set it to FetchValue() instead of trying to determine what that value is. Original code did not set the right server defaults in my setup.
• --ignore-cols ignores special columns when generating association tables. Original code requires all columns to be foreign keys in order to generate association table. Example: --ignore-cols id,inserted,updated.
• Uses the command flask-sqlacodegen instead of sqlacodegen.
• Added support for --notables to only generate model classes, even for association tables
