add DehumidifierDriver

[1saac-k]

Related Issue, PR: #151, #154

This PR is the third split from PR #154. It contains only the DehumidifierDriver and its related unit tests. Since the device wrapper and the HA entity implementation for the dehumidifier are not yet included, there should be no impact on the air purifier.

29 unit tests have been added, for a total of 109 passing tests.

Just a FYI: I found this decompiled function which confirms the category_keysn for humidifier. Perhaps some humidifiers support more features and hence the other keys.

Thank you for sharing. It's interesting to see D codes for plasma and brightness level, which are supported in the air purifier driver. Below is the list of D codes that are not supported — i.e., excluding what I've added in this PR. It might be worth documenting these in an issue or in the docs (docs/~.md) for future reference.

Code	Category
D01	WORK_TIME
D06	SENSOR
D07	PLASMA
D09	LIGHT
D12	3D
D16	DISPLAY_BRIGHTNESS
D17	PLASMA_AIR_PURIFIER

My next PR will focus on updating device_wrapper to support dehumidifiers. Since I'm refactoring the existing implementation, it'll likely take a few days.
