Bug: dataclasses.FrozenInstanceError: cannot assign to field 'id' from version 0.11.28

Think this stems from the release that made bounding boxes immutable. Pinning SAHI to version 0.11.27 works

So this happened due to label remapping being used, so I guess you have used this as well?
When looking and testing the remapping functionalities, I came across a few quirks.
Most notably in the parameter documentation it is said, that the remapping maps label (names) to new ids, e.g. {"car": 1}.
However, in the code it is clear, that the previous ids have to be used and those are then mapped to new ids, e.g {"2": 1}.

I would be interested to see, how you have used the remapping, to see if I have missed something.
