AZTEC: use algorithm adapted from ZXing for optimized encodation

Browse Source 
(ticket #347), props Frank Yellin and Rustam Abdullaev;
   also improve performance of `FAST_MODE`
DATAMATRIX: assert max size on `edges` will fit in unsigned short;
   use MASK for DMRE/SQUARE `option_3` setting
PDF417: assert max size on `edges` will fit in unsigned short
GUI: fix setting AZTEC size and ECC combos if not previously set
manual: fix not mentioning AZTEC re `FAST_MODE`;
  gs1 mode footnote: mention 3940's length; pandoc -> 3.9
test suite: DOTCODE: account for new BWIPP input length guard
