@retry decorators for io operations

[srosenbu]

This might be a not-so-relevant edge case, but when you write data to a network drive (which might often be the case for us) it has happened to me that the network drive disconnects randomly and my simulation stops. Using a package like tenacity, it would be relatively easy to wrap all io functions (like plots for paraview) with @retry to retry the operation acertain number of times with a certain time delay in between trys.

Again, probably an edge case, but it would not be a very intrusive change to the code
