Update Switchbot intergrations PySwithbot to latest

Tags: #<Tag:0x00007fc4179c59e0>

Hello, I would like to know what the process would be to get pyswitchbot updated to 0.9.1 in the SwitchBot integrations? With this update it would allow support for the SwitchbotCurtain, however this might need a now cover.py file to be create but I am not sure.
