Support InferenceData and Stanify

@jandraor's paper on applying Bayesian workflow could be extended with SBC. Currently system dynamics model translators are progressed in parallel (python and R in the linked branch of the library).

This could start from a simple model case study such as SIR and prey-predator, each of which has three and four parameters. New SBC features such as 1. test quantity (likelihood function) 2. dynamic rejection based on gamma distribution can be incorporated. It would be interesting to find discrete value parameter example in the future. Three checks and prior elicitation will be the minimum contents.

Analysis of prey-predator will be mainly documented here.

@Dashadower may I ask for some advice on whether migrating the above file to this repository might be possible? i.e. do you recommend being standalone library from pysd, or might considering combining to python version of SBC package be possible?..
