fixed RRI bug
"0" is an index number it needs to be NULL
cleaned code a little to keep naming convention of other macros.
not defining RRI in the printer.config file defaults it to "NULL"
from my tests it looks like using RRI is not a good idea due to the constant mesh size changing
snipit from klipper code defining relative_reference_index to "none"/null
