please just use the associated functions for the halo2curves types, with some conversion. it is ok on host to enable the halo2curves import always

I would prefer for code maintenance if you just converted to halo2 curves type and called the associated method there. this duplicate code is not good for upkeep

hm, unfortunately halo2curves computes the Gt value for final exponentiation directly and doesn't have a separate residue witness and cubic nonresidue power/scaling factor calculation, so it doesn't seem like there's a good way to calculate these values directly via halo2curves
