Some emulators are trained using data transformations (log, asinh, etc) to improve performance. We normally apply the inverse transform during parameter inference, so the likelihood is always computed in the original, untransformed space. Nathan is currently testing if this could induce biases.

This PR adds some additional flexibility to sunbird to handle posterior sampling in the transformed space. Also slided in some other small things from previous edits that I hadn't commited.
