NIFTy re demo
The nifty.re demo now sets point estimates to showcase this feature: https://gitlab.mpcdf.mpg.de/ift/nifty/-/blob/NIFTy_8/demos/nifty_re.py?ref_type=heads#L202
As the first new nifty.re-users now copy this over to their own script without thinking about what this implies; I am wondering if we should remove it in the demo. @pfrank, @gedenhof, what do you think? Alternatively, we could also add a comment that in many applications, one probably doesn't want to set point estimates or at least would need to adapt the keys to the domain of the model.
