Use child description as sensor name

[Bart]

I am confused as to why the child sensor description string is not used for the name of the sensor. I have a board with many push buttons attached and their names in the sketch are meaningful. Is there a way to automatically have them discovered as, e.g.:

friendly_name: Living Room S 1

instead of

friendly_name: InputBinary1 1 58

I would not have to rename them manually.

This will need a PR to home assistant. I like the idea, so I'll put it on my todo list. PR is also welcome.
