Family.New should not try to determine template file

[eirannejad]

See https://github.com/mcneel/rhino.inside-revit/blob/f6e5ac89bfd80dc5b291abff63770f9ea1fad42a/src/RhinoInside.Revit/GH/Components/Family.cs#L512

The purpose of Family.New is to generate a new family. By packing smart finders into the component, it is becoming unnecessarily complex.

• Family templates are not always installed.
• Even when they are installed, sometimes they are moved into non-standard locations
• Most users that generate families, have customized templates that has company metadata and other information already set

It should be left to the user to determine the appropriate family template they need, or separate this functionality into another component.

The user can decide which template file to use, but in case the template is not specified, the component try to load a Generic Model template. I think is handy for a quick setup of the definition.
