All the various auxillary functions will need updating too, e.g.

• geometries::utils::sexp_col_int()
• geometries::bbox::calculate_bbox()
• sfheaders::zm::calculate_zm_ranges()
  etc...

Design options:

• 'unlist' the list and create a data.frame with an ID column, taken from the named element of the list?
• accept the list as-is and loop over each element (will need to keep track of z/m-ranges, bbox)
