Description
Summary:
QR-transformation reduces posterior correlation improving the performance of sampling. Currently when QR=TRUE, the prior is set on weights for the transformed design matrix. The suggestion is to add an option to allow setting the prior on original weights when QR=TRUE.

Research direction
No files, tests, or entry points are named. Start by locating the QR transformation and prior-setting paths in rstanarm, then determine how an option could apply priors to original weights while QR=TRUE; done means the option is implemented and its behavior is covered by tests.
