VeSync Etekcity Light Bulbs

Please add VeSync Etekcity Light bulbs to HA.
HomeAssistant currently does not support light bulbs in the VeSync integration.
The pyVeSync library does support them already (https://github.com/markperdue/pyvesync/ or alternatively https://github.com/webdjoe/pyvesync_v2), so it’s just the HA component that needs an update.

I finally figured out by myself how to implement the code and just made a pull request to implement this platform.
