This PR aims to extend the parallel reduction capabilities of FlooNoC to allow for barrier operation.

  • pkg: 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 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

Due to the interleave between parallel reduction and offload reduction ( #134 ) some required changes for the offload reduction are already implemented in this PR. The split PR aims to reduce review time.
