GRIDMATRIX: fix byte latch 6 -> 7, & allowing more than one

Browse Source 
non-digit in numeral (both caused misencodation);
  replace `gm_macro_matrix[]` array with calculation (marginally
  slower but saves ~1.4k);
  replace `gm_shift_set[]` use with simple compares (performance);
  change GM_CHINESE/etc defines to numbers so can index into new
  `gm_shift_set[]` array (simplifies mode switching code);
  GM_NUMBER -> GM_NUMERAL, modules -> macromodules_per_dim, various
  other renamings to hopefully more explanatory names;
  various other changes (mostly performance)
test suite: make use of new zxing-cpp diagnostics2 branch Grid
  Matrix decoder
manual: slight clarification of `--gs1nocheck`
BWIPP: latest
