Update state with source variable "absorb_layer". absorb_layer is used to absorb the flow and gradually reduce the flow quantities like pressure and velocity to a fixed value. It is based on: Xu, H., & Sagaut, P. (2013). Analysis of the absorbing layers for the weakly-compressible lattice Boltzmann methods. Journal of Computational Physics, 245(x), 14–42. Jacob, J.; Sagaut, P. (2019): Solid wall and open boundary conditions in hybrid recursive regularized lattice Boltzmann method for compressible flows. In Physics of Fluids 31 (12), p. 126103.
This subroutine's interface must match the abstract interface definition proc_apply_source in derived/mus_source_type_module.f90 in order to be callable via applySrc function pointer.
