  1. [rom] Change the endianness of FORs indices. 

    This backwards-incompatible change is part of the changes between the
round 3 SPHINCS+ submission to the NIST PQC competition and the SLH-DSA
draft standard.

Corresponds to this commit from the SPHINCS+ reference implementation
(consistent-basew branch):
sphincs/sphincsplus@129b72c

  4. [host] Switch SPHINCS+ lib to use our own bindgen library. 

    Instead of using the pqcrypto crate to indirectly access the reference
implementation, we now directly invoke our own bindings for the
reference implementation.

follow.
