Queues: Test Oracles for PIEOs and PCQs

[KabirSamsi]

This PR introduces Python test oracles for Push-In-Extract-Out (PIEO) Queues and Programmable Calendar Queues (PCQs). It also generalizes parts of the oracle generation framework to account for parameters like time and rank being passed in directly.

For further info on these structures, please consult the notes that I and @anshumanmohan's have put together on PIEOs, PCQs and PIEO Trees which also discuss the PIEO-PCQ implementation I have gone for here.

Awesome stuff, and congrats on getting your errors sorted out! I have left a number of comments for you to chip away at. Mostly they are for readability, and in one case I am suggesting a library implementation instead of a hand-rolled one. But the first step is what you have done just now: writing it out by hand! Now that you know it works, you can more confidently try out a library implementation to see if it does what you need. This handwritten version will also be invaluable when coding it up in Calyx.

Also, please use the command line to resolve your conflicts with main. Github is guiding you through it below, and I can show you during our 1:1 later.

Since my last comment, I've made a handful of changes to fix the CI compiler & memory allocation errors that had started again post the merge. All should be fixed now, though.

@anshumanmohan whenever you have a moment, I've put in all the edits you requested and some of the new functionality. Please let me know if anything else is needed!

[anshumanmohan]

Woohoo! Nice stuff, and thanks for doing up the simple/universal version in addition to the other two! I have a few comments inline to try and clarify the code for myself, but otherwise this is looking very close to done :)

[KabirSamsi]

I have added all the requested changes, are clarified any questions in the discussion above. Please let me know if anything else is required!

[anshumanmohan]

Thanks! Merge at will!
