I would prefer if we come up with a consistent naming, e.g. SSL_ for the ssl losses, so that we do not need to maintain an explicit list here.

Why do we need this here? This should be apparent from the masking--forecasting has no mask on the target.

Description
Draft implementation of per-cell LeJEPA with SIGReg loss. LeJEPALoss should probably just go under the LatentLoss class, to do. Also needs checking.
We have a "SelfTeacher" since we don't do any stop grad/EMA etc. with LeJEPA.
