Add Elechico / Chico CCIB001-CC1177D ice bath heat pump controller (#5501)

* Add Elechico/Chico CCIB001-CC1177D ice bath heat pump controller

* Address review: F-unit redirect, fault_code attribute, drop binary_sensor name

- temperature/current_temperature redirect to dp25/dp26 with 37-113 °F range
  when temperature_unit is f (dp17)
- fold "Fault code" into a fault_code attribute on the problem binary_sensor
  instead of a separate sensor entity
- drop the binary_sensor name so HA's class translation is used
