not sorting msd_stderrs when sorting msds

times, msds = hf.parallel_sort(times, msds)

Also do we need to calculate the lifetime error since it is guaranteed to be 0?

For longer values of lifetime this may not be true: There's also a cutoff after a certain number of moves (10K?), which may happen before lifetime is reached.

I will double check but I think currently the function is using the user provided lifetime--a single value with no error--and not the actual lifetime of the carrier.
