Z raise on homing override **feature request**

Add varilable from sample_retract_dist for probes to allow Z raise on homing_override when homing individual axes

Just a blip below to add to homing_override.py taken from zcalibrate: use sample_retract_dist if available close #748 · jordanruthe/KlipperScreen@0ca410a · GitHub

klipper_cfg = self._screen.printer.get_config_section_list()
    for probe_type in self.probe_types:
        if probe_type in klipper_cfg:
            probe = self._screen.printer.get_config_section(probe_type)
            if "sample_retract_dist" in probe:
                z_hop = probe['sample_retract_dist']
