Add the Levoit 450S smart humidifier to the existing VeSync integration

Feature Requests
1

I did a search and see requests to add many of the models and I didn’t see this one:
LUH-O451S-WUS, Levoit OasisMist® 450S Smart Humidifier
Product web page

I connect to other devices with the VeSync integration

Thanks!

This custom integration works with the Levoit 450S Smart :wink:
