feat: Add support for LUH-N615S-WUS NeoClassic 650s

[s7726]

The normal humidifier functions are working.
Need to get the "NightLight" working, looks like I need to snoop the API. Also Need to implement the AutoPref types and snoop how to set those.

Creating the PR in case anyone feels like helping or providing feedback on the progress.
