…rrier operation * hw: Extend package with configuration for parallel and offload reduction * hw: Introduce LSB-And operation in ```floo_reduction_arbiter.sv``` * hw: Add parallel reduction support to the ```floo_router.sv``` * hw: Add all parameters relevant for the parallel and offload reduction to the ```floo_nw_router.sv``` / ```floo_router.sv``` without changing the port-list * hw: Add support to the ```floo_nw_chimney.sv``` (merged from commit hash: 4a7f9a1 by raroth)
* hw: add sequential reduction controller to FlooNoC * hw: add generic offload port to all routers * hw: added small parameterizable ALU to FlooNoC which can be used to run simple Integer operation (Add / Mul / Min / Max) * misc: reduction controller supports multiple configuration depending on area / performence requirements. * dataflow: any offload collective flit is brunch off at the input of the router and forwarded to the reduction logic. The final reduced flit will be merged into the normal datastream with an additional slave port on the reduction arbiter / wormhole arbiter. (merged from commit hash: 4a7f9a1 by raroth)

* When it is dedected that the flit will leave the reduction controller after the reduction then the controller starts with the next reduction even if it is not finished yet.

This PR aims to further enhance FlooNoC by implementing offload reductions.
hw: add sequential reduction controller to FlooNoC
hw: add generic offload port to all routers
hw: added small parametrisable ALU to FlooNoC which can be used to run simple Integer operation (Add / Mul / Min / Max)
misc: reduction controller supports multiple configuration depending on area / performance requirements.
dataflow: any offload collective flit is brunch off at the input of the router and forwarded to the reduction logic. The final reduced flit will be merged into the normal data-stream with an additional slave port on the reduction arbiter / wormhole arbiter.
