Switch Block Collections Attribute Error #20

due to the project being updated to use python 3.11 there was an issue with importing the Collections module in the block_types/switch_block.py file, causing AttributeError: module 'collections' has no attribute 'Iterable'

I was able to fix it by replacing import collections with import collections.abc as collections

I have not found any other instances of this being an issue yet but i thought i would bring it to your attention.

thanks!
