-The function computes the sum of the signed elements of the BLS12-381 curve. The input is an arbitrary number of pairs $(p_i, s_i)$, where $p_i \in E(F_p)$ is point on elliptic curve and $s_i \in \textbraceleft 0, 1 \textbraceright$ is the point sign. The output is one point from $E(F_p)$ equal to $\sum (-1)^{s_i}p_i$.

 The $E(F_p)$ curve,  points on the curve, multiplication on -1,  and the addition operation are defined in the BLS12-381 Curve Specification section.
 
 Note: we take as input any points on the curve, not only from   $G_1$
