Computes multiexp on alt_bn128 curve using Pippenger's algorithm \sum_i mul_i g_{1 i} should be equal result.
Parameters
• value: Uint8Array
sequence of (g1:G1, fr:Fr), where G1 is point (x:Fq, y:Fq) on alt_bn128, alt_bn128 is Y^2 = X^3 + 3 curve over Fq. value is encoded as packed, little-endian [((u256, u256), u256)] slice.
