Add Annotations from the original Raw object that is preserved in Temporal, or Epoch Connectivity

[adam2392]

Describe the problem

Right now, if there are annotations defined on a Raw object, e.g. a seizure occurs at time point 60 seconds for duration 10 seconds, then that annotation is lost in a connectivity object. If the connectivity object somehow preserves time (e.g. continuously as a Temporal*Connectivity object, or as epochs as a Epoch*Connectivity object), then the annotation should map to a specific time point, or epoch.

The main issue is mapping to a specific epoch.

Describe your solution

We have to wait for a solution to come out of mne-tools/mne-python#8376 (comment)

and then copy that logic flow for our Epoch*Connectivity data structures.
