@rohanbabbar04 interesting that the ubuntu mpich with 9 seems to take ages, not sure if it is related to the PR new tests... I can make a fake PR and see Looks like also with no change to the codebase a few of the mpich/9 actions are slow #202 |

Motivation
This PR introduces support for nested
StackedDistributedArray.In other words, in the current setup one can stack multiple
DistributedArrayinto aStackedDistributedArray. However as part of this effort to introduce support for distributed proximal operators and solvers in pylops-mpi, it turns out that in some scenarios one requires to created nestedStackedDistributedArray, meaning that one of more elements of aStackedDistributedArrayareStackedDistributedArraythemselves.Some changes are required for basic operations (eg +, -, *) to work and this PR provides them.
