// on each MPI rank, this writes an HDF5 file which contains that
// information which can later be read in by read_source_bank
// (defined below). If you're writing code to write out a new kind
// of particle bank, this function is the one you want to use!
//
// For example, this is used to write both the surface source sites
// or fission source sites for eigenvalue continuation runs.
//
// This function ends up calling write_source_bank, and is responsible
// for opening the file to be written to and controlling whether the
// write is done in parallel (if compiled with parallel HDF5).
//
// bank_index is an exclusive parallel scan of the source_bank.size()
// values on each rank, used to create global indexing. This vector
// can be created by calling calculate_parallel_index_vector on
// source_bank.size() if such a vector is not already available.
//
// The source_bank variable is used as work space if MPI is used,
// so it cannot be given as a const span.
