Add/update/deprecate symbols to align the symbol set with the standard. Color tones are adjusted in this commit but not yet renamed and reordered in line with Printing And Colour Definitions.
Colors renamed and reordered in line with Printing And Colour Definitions. Colors that are not defined in the standard are marked with "(extra)" suffix in their name.
Some of the CMYK values calculated from spot colors differ from the values stated in Printing And Colour Definitions. We provide custom CMYK values in these cases to follow the standard.
Implementation of the changes from September 2024.

On popular demand, here comes the latest ISOM 2017-2 symbol set for OO Mapper. The patch set is divided into four sections for manageable review and/or debugging.
First is the change of symbols and color tones without reordering. Second is the reordering and renaming in the color table.
Third is the implementation of CMYK-only printing. Mind that Printing And Colour Definitions no longer define spot color tones and only define CMYK values in an unknown color space. As a result, not all colors can be calculated from a "defined" base (previously) color and the values have to be entered manually. That means
symbol_set_tgenerator has to be educated about this divorce between spot colors and CMYK values. Fourth patch is the adjustment of brown color tones made in September 2024.Regarding symbol numbering, the last ISOM update hit the mapping software vendor's symbol numbering conventions right on the head. The standard introduced new symbols with dots which collides with the established standard of distributing symbol variants (e.g. black and green vegetation boundary) and parts (contour line and its slope line) as dot-code sub-symbols. This patch set multiplies the ISOM numbers after the dot by a hundred to make it clearer that the symbol is not a vendor symbol set extension but the upstream base symbol. And yes, I hear you. Mapper has three levels of symbol numbering. Still the fat numbers with the three-digit second level appear more practical to me than the necessity of counting dots on screen to decide if a symbol number has two or three levels.
As usual, this patch set is an offer from my side. Either propose changes and I possibly implement them or rework it to your liking. Of course, there might be bugs in the definitions. I'll be happy to fix them.
