This adds a second USB configuration to the e1-tracer firmware. This configuration is closer to the USB configuration of an icE1usb and hence paves the way for using osmo-e1d with the tracer. The main conceptual difference between the existing "legacy" configuration and this new "e1d compatible" configuration is to have two USB interfaces, one for each direction of the traced E1 interface. Each interface has its own separate two altsettings, one for the disabled and one for the enabled state. Unmodified osmo-e1d will not work straight away with this, as it expects ISO OUT and ISU Feedback endpoints, which a pure rx-only tracing device of course doesn't have.

Firmware for iCE40 based board ============================== The icE1usb, icE1usb-proto and e1-tracer boards are running very similar gateware, all based around a PicoRV32 RISC-V softcore supported by custom hardware cores to deal with USB and E1.
