Prevent Homing on Temperature Above x

[zzing]

I would like to be able to prevent my hot end from homing (where the nozzle would touch the bed, not necessarily max end) when it is above a certain temperature.

The purpose is to prevent a hot nozzle from touching the bed and causing an issue either in the case of a strain gauge and piezo or the accidental crash on a normal z probe.

This will be possible when conditional GCode is supported by RRF.
