Implementations for 3D and Parallel

[EomAA]

Hi,

I just have come across your paper on "A 55-line code for large-scale parallel topology optimization in 2D and 3D".
It is really great to see this work for me, because I am a new student interested in this field.

In this github, it seems only the 2D implementation is uploaded.
So I am wondering if you plan to upload the 3D bridge problem in Figure 10 as well as the parallel implementation things using mpirun. If you upload those implementations, it definitely helpful for many students including me who really would like to jump into this field.

Thank you.
