This adds support for different widths on each port and adds the ability to disable routes within the crossbar. Both of these features allow for FPGA resource savings. These features are controlled by the new parameters PORT_WIDTHS and ENABLED_PATHS. Unused routes will have the associated logic removed. A new testbench adds support for testing different port widths and disabled routes. It also adds more rigrous testing of the crossbar. Original-commit: 18bf81d91055b68765c44ca86a2cbcfa9704c749
