Version 0.7.0

Changed

• Renamed saffier-admin to saffier.
• Deprecate saffier-admin. Now you can simply call saffier with the same commands
  as before.

Added

• New shell command that allows interactive shell with saffier models.
• New SAFFIER_SETTINGS_MODULE allowing to create and pass specific and unique settings
  to any saffier instance.
• Added support for ipython and ptpython for shell access via saffier.

Fixed

• Linting and formatting issues with Ruff.
• Bug with ReflectModel. A ReflectModel might not need all the fields from the database and the mapping should reflect that.
• run_until_complete issues fixed with nest_asyncio.
