Move D2Commands/output into separate module

To speed up the compilation process and to modularize the codebase further create a separate module for the `output` classes, ideally with a more general name.

Start by inspecting the D2Commands/output directory and the project’s module configuration to identify the output classes and their dependencies. Define a suitable general module name, move the classes there, and verify that the project still compiles with output functionality intact.
