`requiredQubits` and `requiredResults` attributes are not added

[RolandMacDoland]

Previously, requiredQubits and requiredResults were generated from pyqir-generator. These attributes are important to us to compile further down to the devices. Is it possible to re-add the in the generation ?

These were removed in #147, since QAT can add them itself. But it sounds like you're sending a PyQIR-generated program directly to your internal compiler without going through QAT, is that right? I agree it'd make sense for PyQIR to still be able to add them in that case.
