Summary: This adds support for untransforming observation features in Relativize that do not have a trial index. This can occur when the Modelbridge does not use TrialAsTask and there are multiple SQ observations (e.g. for different trials) and we try to untransform the predictions for arms in a GR.

Summary:

This implements a transform for adding `start_time` and `duration` as features for modeling. Currently, this adds them as `RangeParameter`s (to unblock time-sensitive applications), but in the future it would be good to revise this with a better treatment of non-tunable contextual information.

`duration` appears to lead to better model fits on the synthetic example (notebook) than using `end_time`. This also works better than using the midpoint between start time and end time.

Differential Revision: D57119551
Summary:

This adds support for handling pending observations that were generated by a Modelbridge that did not use the TimeAsFeature transform and therefore does not have start_time and end_time set in the observation features.
