I hate that I do not understand why the Gitlab runner is so slow

Pipeline #22872 failed with stage
in 5 minutes and 18 seconds

- New collision kernels `BGKwithBuickGreatedStream!` and `BGKwithGuoStream!`, Buick and Guo use different force corrections.
- Performance tests for the collision kernels, `BGKwithGuoStream!` is the slowest option, further details see [collision.jl](test/collisions.jl).
- The gradient of the pressure is now calculated with a circular padded array and is called `h∇p!`.
- Performance tests for all available forces, `slippage!`, `thermalfluctuations!`, `h∇p!` and `inclinedplane!`, see [forcing.jl](test/forcing.jl)
