Write a single row of data to the reductions file without the need to register or reduce anything, e.g. from a singleton component or from a specific chare.
Use observers::Actions::ContributeReductionData instead if you need to perform a reduction before writing to the file.
Invoke this action on the observers::ObserverWriter component on node 0. Pass the following arguments when invoking this action:
subfile_name: the name of the h5::Dat subfile in the HDF5 file. Include a leading slash, e.g., /element_data.legend: a std::vector<std::string> of column labels for the quantities being observed (e.g. {"Time", "L1ErrorDensity", "L2ErrorDensity"}).reduction_data: a std::tuple<...> with the data to write. The tuple can hold either doubles or std::vector<double>s and is flattened before it is written to the file to form a single row of values. The total number of values must match the length of the legend.
