This step compiles the AST into an executable function, either for CPU or GPUs. This function
behaves like a normal Python function and runs one LBM time step.
Each stage (apart from *Function*) also adds its result to the given `LBMConfig` object. The `LBMConfig`
thus coalesces all information defining the LBM kernel.
The function :func:`create_lb_function` runs the whole pipeline, the other functions in this module
execute this pipeline only up to a certain step. Each function optionally also takes the result of the previous step.
