raster/vector: fix BARCODE_BIND_TOP trumping BARCODE_BOX

Browse Source 
backend/tests/fuzz: update "fuzz.h" to take `option_3` min/max;
  update `INPUT_MODE_MASK` & `OUTPUT_OPTIONS_MASK`;
  set `height`, `border_width` & `output_options` from input
  (removing `Z_FUZZ_SET_OUTPUT_OPTIONS` conditional) and call
  `ZBarcode_Encode_and_Print()` instead of `ZBarcode_Encode()`;
  support standalone builds of "fuzz_data" & "fuzz_gs1" with
  `Z_FUZZ_MAIN_READ_ARGV_1` macro;
  update "fuzz_gs1" & "fuzz_gs1.dict" to better test caret/raw
  modes;
  gen_corpora: add `output_options`, `height` & `border_width` &
  find (3rd) from fuzz_data of BIND_TOP | BIND_BOX bug
