dataclass does not accept union of dataclasses?

[victorgabillon]

thanks for this amazing library!

Describe the bug
It is not possible it seems to have the dataclass argument of the from_dict method to accept a union of class

To Reproduce

@DataClass
class A:
x: str

@DataClass
class B:
y: int

data = { 'y': 1 }

result = from_dict(data_class=A|B, data=data)

Expected behavior
result woud be B(y=1)

Environment

• Python version: 3.10
• dacite version: 1.8.1
