  RMQR/ULTRA: set `option_1/2/3` to values used in encodation
  ("Feedback options"), and add new access methods
  `encodedOption1()` etc. to Qt Backend, and use in GUI to provide
  better feedback on "Automatic" selections
- AZTEC: give more precise warnings in low ECC situations, and
  indicate via `option_1` by setting to -1 (min 3 words), 0
  (<5% + 3 words) (`ecc_ratio`)
- set_height: fix non-compliance false positives by using epsilon
  in checks (prompted by CODABLOCKF non-compliant warning for
  zint-generated compliant height - floating point `rows` mult !=
  `zero_count` div; one test regression for CODE93);
  better warning messages on non-compliant heights (min/max)
- manual/man page: fix DATAMATRIX Sizes tables "28 12x26" ->
  "27 12x26"
- GUI: AZTEC/CODEONE: add Zint versions to comboboxes
- DOTCODE: improve error messages re size too small/large
- ULTRA: better ZINT_TEST codeword dump (ZINT_DEBUG_TEST)
- general: various tabs -> spaces; prettify main .rc files;
  trailing spaces; small amount of code fiddling (CODE16K)
