LM393 light sensor module support

[edugrt]

Hello @rsg98!

Would you consider to support the LM393 light sensor module as well? I see that it already works using other types of accessories such as the contact sensor, at least in a basic way. If I create an automation to turn on a light using the readings from the pin to which the LM393 is attached, the light turns on and off when there is little light or regular light in the room.

Supporting the LM393 as an actual light sensor would allow us to automate things based on the actual LUX readings.

Thank you!
