gitlost effb13cab8 DBAR_OMN/LTD: replace unnecessary large_uint with uint64_t 
DBAR_OMN/LTD/EXP: add helpers `dbar_xxx_group()` to calc groups;
  `dbar_widths()` -> dbar_getWidths()` & make `noNarrow` boolean;
  new helper `dbar_widths()` interleaves;
  various other refactorings, fiddlings etc.
DBAR_EXP: `dbar_date()` -> `dbar_exp_date()`
upcean: make `cc_rows` const
