Problem

In a situation where you only need to take one value in FSMContext handler, you need to write 2 lines of code to take value

Possible solution

Add a get_value function for FSMContext that takes value by key

# before
data = await state.get_data()
name = data["name"]

# after
name = await state.get_value("name")

# i think
name = await state.get_data()["name"] 

wouldn't that work? :3
