Hopefully this fixes the -1 readigs we were seeing in the previous driver now that we are reading the chips independently. This fix allows us to remove the LOAD_CELL_CALIBRATE TARE=TRUE hacks I added to macros.cfg as all probing moves call
LoadCellPrimitives.tare() unconditionally.
Also updating sdo_pins to dout_pins to be consistent with the datasheet and the hx71x driver.
