Add WF4C_WF6C (Koenkk#4749)

* Add support for ABL Juno Connect Wafer lights

Tested with the 4" Contractor Select Smart Wafer Downlight, but I believe there are multiple form factors that all share a single Zigbee model

- [Contractor Select Smart Flat Wafer Downlight](https://www.acuitybrands.com/products/detail/1755360/juno/contractor-select-smart-flat-wafer-downlight/4-and-6-led-smart-wafer-downlight)
- [Contractor Select Smart Regressed Wafer Downlight](https://www.acuitybrands.com/products/detail/1755363/juno/contractor-select-smart-regressed-wafer-downlight/4-and-6-led-smart-wafer-canless-downlight)
- [Smart Adjustable Wafer Downlight](https://www.acuitybrands.com/products/detail/1755366/juno/smart-adjustable-wafer-downlight/4-and-6-led-adjustable-smart-wafer-downlight)


Not sure what makes sense for labeling of vendor/model/description but I used my best judgement. Feel free to modify!

* lint: fix spacing

* Update acuity_brands_lighting.js
