Friet AE hardware implementation compatible with NIST LWC API

This is the hardware implementation of Friet AE cipher compatible with the NIST LWC API. There is already an hardware implementation available at https://github.com/thisimon/Friet . However, the original version has a customized interface, in this version we adapt it to work with the NIST LWC API.

The Hardware implementation is compatible with the hardware LWC API from https://cryptography.gmu.edu/athena/index.php?id=LWC The implementation done in Verilog and doesn't use any files provided by the LWC API.

While the Friet LWC API hardware doesn't have a paper, you can cite the original Eurocrypt paper, since the inner core is the same.
