Subject: [PATCH] fix: enable CreateDefaults on DxfReader to fix missing
 ACAD_GROUP dictionary

SolidWorks DXF exports don't include the ACAD_GROUP entry in the Named
Object Dictionary. Without it, AutoCAD reports "GroupTable dictionary was
not defined in NamedObject dictionary" when opening the file.
