feat (hysen_hy101rf_thermostat): support Kekotek KTF017802

This device is missing the external sensor and 3 related dps,
otherwise identical. Make these 3 entities optional and hidden if
unavailable.

Split program out into text entities in case any user wants to layer
programming on top. These dps do not seem to be reported by the device,
but probably can be set, and maybe can have the current values coaxed out
somehow. Since they aren't useful without advanced investigation, the
entities are disabled by default.

Issue #4468 / PR #4477
