cast_in Exception, when writing description property

[juraj3579]

Hello,

after I decided to switch my application to async BAC0 (which made me some headaches, but in the end I could manage it somehow :-) ) I've stumbled upon a problem when trying to write description property of an object.
I could localize the problem to the cast_in function in the Text.py module.

_venv\Lib\site-packages\BAC0\core\functions\Text.py", line 48, in build_text_write_request
    _value.cast_in(CharacterString(value))
TypeError: Any.cast_in() missing 1 required positional argument: 'element'

Checking back in code of BACpypes3 i found out, that the Any() value should be defined with argument or with none.

so changing the definition of _value in the Text.py from

_value = Any()

to

_value = Any(None)

solved the issue for me. Maybe you can checked that out and merge the change later on.

Thanks for that ! Believe me I feel your pain regarding async. It is a pretty wild change of mindset...
