Add advdiffreac.ipynb for demo

[RequieMa]

First trial for #94
Used adios4dolfinx for reading NS solutions (Personally, store solutions from each time step in a form of "./Flows/flow_function_{i}". There may be a better way to store all time sequence in one folder)

@BillMaZengou I guess the mesh file is missing. I tried with no luck with adios4dolfinx-0.7.3.

$ docker run -it --rm -p 8888:8888 ghcr.io/cpp-review-dune/introductory-review/jupyter-dolfinx
$ git clone https://github.com/BillMaZengou/dolfinx-tutorial.git
$ cd dolfinx-tutorial
$ git switch Advect_diff_Eq_Demo
$ startJupyter &

Could be nice be formatted with nbQA.

Hi @RequieMa, I did some progress from your advance in this branch, mostly from here, I noticed that the mesh was taken from Solving PDEs in Python – The FEniCS Tutorial Volume I and implemented in chapter2/ns_code2.ipynb so I added gmsh.write("mesh_flow.msh") there in order to read sucessfully. The setup is python 3.12.3, dolfinx 0.8.0, petsc 3.21.2 and adios4dolfinx 0.8.1.post0. Could you try in local or in remote here over Arch Linux.

Ive made major updates to adios4dolfinx that would make checkpointing easier for multiple, tome-dependent solutions:)

Sorry, I hadn't had time to update this since then. I will double-check carlosal1015's change and jorgensd's updates of adios4dolfinx. Hopefully, I will complete it soon
