Update syntax to Python >=3.9

[hagenw]

Updates syntax to Python >=3.9 by removing the use of typing (with the exception of typing.Self in audformat/core/table.py type alias definitions in audformat/core/typing.py, and typing.TYPE_CHECKING in audformat/core/column.py).

Summary by Sourcery

Enhancements:

• Use native Python 3.9 type hinting syntax instead of the typing library.
