Description

The intention is to move the implementation of eng_stan() to the rstan package, so that the engine implementation can evolve as the rstan package evolves.

As an example, we do this with the reticulate package here:

https://github.com/rstudio/reticulate/blob/master/R/knitr-engine.R

Research direction

Start by comparing the requested rstan implementation with reticulate's R/knitr-engine.R example and inspect where eng_stan() currently lives. Determine the rstan entry point and existing tests for the engine; done means the implementation is provided by rstan and works with knitr as intended.
