v0.14.1

Changed

• The max_integer and min_integer flags have no value, because integers are unbounded:
  current_prolog_flag/2 fails for them in both modes, as in SWI-Prolog, and flag enumeration
  omits them. They used to report the tagged-integer promotion thresholds, which larger integers
  exceed. set_prolog_flag/2 raises domain_error(flag_value, Flag+Value) for them instead of
  permission_error(modify, flag, Flag). The max_tagged_integer and min_tagged_integer
  evaluables still name the thresholds.
