Split a string into fixed-length parts.

linesplit.fixed(
  cline,
  length_per_part,
  num_parts_expected = NULL,
  error_tag = NULL
)

`cline`	character string, the input line
`length_per_part`	integer, number of characters per part
`num_parts_expected`	integer, the number of parts. Leave at NULL if this is not known.
`error_tag`	optional character string, how to identify the line in a parsing error message. Could be the line number, or whatever. Only relevant if 'num_parts_expected' is not matched.
