Bump evohome client to 0.4.17

[zxdavb]

Proposed change

The client library is bumped because it has several bugfixes.

In addition to addressing #101355, the integration can now handle situations when min/max setpoint can't be retrieved from the vendor.

That is, in the updated client library, these setpoints are float | None, but in existing HA integration, they're just float. In the client:

    def max_heat_setpoint(self) -> float:
        ret: float = self.setpointCapabilities[SZ_MAX_HEAT_SETPOINT]
        return ret

... becomes:

    def max_heat_setpoint(self) -> float | None:
        if not self.setpointCapabilities:
            return None
        ret: float = self.setpointCapabilities[SZ_MAX_HEAT_SETPOINT]
        return ret
