New function: Antonio's Convergent Acoustic Neumann Series

[bencox]

Description

Make a k-Wave-i function for Antonio Stanziola's first-order iterative solver. It's currently available in github and a paper is here: https://arxiv.org/html/2507.16087v1

We've considered calling is CANS: Convergent Acoustic Neumann Series. Maybe the Matlab function would be convergentAcousticNeumannSeries.m?
