There are many variants of LCD displays using different pin assignments of the PCF8574 chip.
For a list, see e.g. the HD44780 library which lists 4 variants, and I personally own one with yet another.
This adds new constructors and class variables to allow changing the pin layout.
_sendNibble() and _write2Wire are updated accordingly.
