More work on "forward" capability
The current implementation of the forward model requires initializing an LSForce object, but there is no way to do that without data at present. That doesn't work for people wanting to run the forward model to create synthetic data for an arbitrary force-time function, they would have to fake some data. Consider adding a way to access the forward model by just initializing stations without any data (real stations for now if syngine won't work for fake stations) for which the forward model should be run. Also, add an example in a notebook for the use of the forward model.
