C implementation of the (derandomnised) X-Wing hybrid KEM as defined in draft-connolly-cfrg-xwing-kem and analysed in https://eprint.iacr.org/2024/039 by Barbosa et al.
This reuses code from some C files and headers (including the MLKEM implementation) and the Makefiles from https://github.com/formosa-crypto/hakyber. I cannot find the license for said code, so I am acknolwedging it here. Whenever the license is uploaded, I will refelct those changes.
Libsodium is also a dependency.
