Consistent parameterization w.r.t. updating reference windows

- kdqtree and HDDDM have different default behaviors: static window for the former, updating window for the latter. This choice was because kdqtree's transform is expensive to run.
- It would be good to have consistent default behavior across all detectors, or at least something like `auto_update=True` in the parameterization, so it's more explicit what behavior will occur by default.
