Optional compile-time conversion from homogeneous object collections.

This module is deliberately not exported by the terminal_table façade. Import it when object reflection is useful:

import terminal_table/typed_data

let table = tableFromObjects(records,
  tableColumn(name, "Name"),
  tableColumn(score, "Score", formatScore))

Column specifications select and order fields. An omitted field is hidden. A formatter must have the signature proc(value: FieldType): string.
