Example accessing Section Group data.

With split dwarf your libdwarf calls after than the initial open are done against the base Dwarf_Dbg and libdwarf automatically looks in the open tied dbg when and as appropriate. the tied-dbg can be detached too, see example3 link, though you must call dwarf_finish() on the detached dw_tied_dbg, the library will not do that for you..

Section groups apply to Elf COMDAT groups too.
