Request: Allow loading of data while the simulation is still running

[AnujKankani]

Right now if you load simulation data while the simulation is still running you can get the error "xarray.core.coordinates.CoordinateValidationError: conflicting sizes for dimension 't': length 4994 on the data but length 4995 on coordinate 's'" depending on where in the timestep the simulation is. If there is a built in way to ignore the last output file when loading data, so that we can check on simulations while they run, that would be very helpful!

Thanks!
