fix lsf_reset - ZERO macro can't handle a pointer as it would only memset the size of the pointer, not the size of the entire struct
Add startup notice & update host temperatures while waiting
Right now G26 doesn't send a notice to the host that it's running. It's
not until the heaters are at temperature that you know for sure if it's
running or not.
Added host temperature prints so that someone watching the host
interface will see the temperatures change during the warm up period.
Updates are sent every 5 seconds.
Pretty much... The code is in place. Still more work to do. But it
has a lot of hooks and variables in other code, so commit and merge
before I pick up a million 'Conflicts'.
- Make all `unified_bed_leveling` data/methods static
- Move some UBL-related variables into the class
- Replace `map_[xy]_index_to_bed_location` with `mesh_index_to_[xy]pos`
