  h5_list,
  target = "matrix",
  add_uuid = TRUE,
  replace_barcode = TRUE,
  retain_original_barcode = TRUE,
  add_name = TRUE
)

`h5_list`	a list object generated by running rhdf5::h5dump() on a 10x HDF5 file.
`target`	the group name for the matrix within the h5_list to use. Default is "matrix", which is used by 10x.
`add_uuid`	a logical indicating whether or not to add a uuid generated by ids::uuid(). Default is TRUE.
`replace_barcode`	a logical indicating whether or not the new uuid should replace the barcodes slot. Default is TRUE.
