A bugfix for issue #739, which was brought up by @olliestephenson.

When saving time-series residuals during timeseries2velocity.py, the code did not ignore the excluded dates. It writes residuals for all the dates we haven't excluded, leaving the final N date entries empty (where N is the number of dates we have excluded). This means that the residuals no longer line up with the correct dates.

Now the code instantiates the output time-series residual hdf5 file with the correct number of dates, accounting for the excluded dates.

This bugfix is a realization of the suggested solution from @olliestephenson, in which we pass the shape of the timeseries with the excluded dates removed to layout_hdf5 via the ds_name_dict argument.
