Added a variable-base sign-scalar multiplication called
mul_sign.This multiplication inputs a scalar and a base and returns
[scalar]base.The scalar must be in {-1, 1}.
To evaluate this multiplication, we re-use the
q_mul_fixed_shortgate.This gate is used in the fixed-base short signed scalar multiplication to apply the sign of the scalar on the result of
[magnitude]base.
