Improve the handling of Enums

[ndonkoHenri]

This PR mainly attempts to fix #3736 (comment). The heavy enums (colors and icons) were imported in types.py, which might have been the cause.

Also, Enum vs String comparisons are now possible, ex: ft.Colors.AMBER == "amber"

Summary by Sourcery

Refactor enum handling to allow string comparison.

New Features:

• Introduce ExtendedEnum for enhanced enum functionality.

Enhancements:

• Change Enums to inherit from ExtendedEnum.
