Make Crafting Input Bus / Hatch compatible with some non-GPL multis (#2266)

* Add crafting input bus items to getStoredInputs

* Add crafting input hatch fluids to getStoredFluids

* Respect internal input isolation

* List.of -> Arrays.asList

* Skip fluids on non-supporting bus

* Fix NPE

* Change return type to Optional & add Slave support
