Update mark of assemblies

Automatic duplication of the Rebar Host Mark parameter into the assembly.

This add-in is intended for automatic duplication of the Rebar “Base mark” parameter in the assembly, since the BOMs must specify the number of assemblies for each wall separately.
This parameter is user-defined, type is text, the parameter name is set in the window of the same name after calling the add-in. Introduced for filtering wireframes in Rebar Host Mark by the base label of a given wireframe.
