Sanjun Steamroom (#4828)
* Add files via upload
YAML for Sanjun Steamer
* Update sanjun_steamer.yaml
* fix(sanjun_steamer): handle default for light effect
Default keyword is for setting when no value was supplied by HA.
For the other direction, we need to define a mapping with no dps_val.
Change the non-effect setting from "red" to "off", and direct to white by default, though any other setting is also mapped to "off" by the default mapping.
