getArchiveFileDescriptors

Gets the list of archive file descriptors. See `setArchiveFileDescriptors()`. NOTE: The caller must not close the file descriptors returned by this function, as they are owned by the `TileStoreImportOptions` instance and will be closed automatically when they are no longer needed. If the caller needs to keep the file descriptors open, it should either keep the owning `TileStoreImportOptions` instance alive, or duplicate the file descriptors before use. The values of the file descriptors returned by this function will be different than the values inputted in `setArchiveFileDescriptors()`, since the input file descriptors are duplicated for internal use.
