[RTL] Correct string handling for type key in NAMING_KEYS (#1960)

* Correct string handling for type key in NAMING_KEYS

Extend class structure RTL_433device and modify code to create correct state topic in discovery message to support sensors, that send type key as well as sensors, that don't. Actually only TPMS sensors use type=TPMS.

* Try to correct format failure.

* Remove trailing spaces
