Awesome, will help a lot I think for my machine, UBL G29 takes enough time that my bed cools quite a lot. |

This PR adds an option to wait for the bed to heat back up between each probe. This applies to bed leveling and probe-based homing.
The reasoning behind this is that when heaters are disabled the bed can cool slightly but doesn't have enough time to heat back up between probes.
This code checks to see if the bed is at target temp. If it's below target temp, it will poll every 200ms until it reaches the target.
After a lot of testing I've determined that it helps accuracy of the probe quite significantly on some beds (those that tend to cool faster).
