Add support for Xiaomi Button Switch model WXKG12LM

Hi,

I bought an updated version of Xiaomi Button that support double click and features a gyroscope. The “basic” button (models WXKG11LM and WXKG01LM) are supported, but the new one (model WXKG12LM) is not.

Home Assistant can detect, only, click, long_click_press and hold events. There is no support for double_click nor shake.

Is it possible to add support for these click_type?
