[2023/06/28] netDxf 3.0 Release

[2023/06/28]
* Added the property WorkingFolder to DxfDocument.SupportFolders. When a file is loaded or saved, it will hold the full path where the file resides, by default it points to the current System.Environment.CurrentDirectory when the DxfDocument was created.
* Now you can change the Name and Style properties of LinetypeShapeSegment classes.
* Deleted the TextStyle constructors public TextStyle(string font) and public TextStyle(string fontFamily, FontStyle fontStyle), now you must also provide the table name.
* Deleted the ShapeStyle constructor public ShapeStyle(string file), now you must also provide the table name.

+* Now you can change the Name and Style properties of LinetypeShapeSegment classes.

 * Removed the taget frameworks netstandard2.1, netcoreapp3.1, and net5.0. Manually edit the netDxf.proj if you need them.
 * Reworked how the references to a TableObject are tracked. Now they are internally stored in a dictionary instead of a list. While this will make adding entities to the document a little slower removing them will be much faster. See the sample TableObjectReferences().
 * Add the method GetReferences to classes that inherit from TableObject. It returns the same list as the GetReferences method of its respective collection. See the sample TableObjectReferences().
