Pairings can't be added

[FilipLaurentiu]

What happened?

The library can't be used to add pairings result together. This can be helpful for off-chain testing

Code that produced the error

from py_ecc.bn128 import G1, G2, multiply, pairing, add

p1 = pairing(G2, multiply(G1, 4))
p2 = pairing(multiply(G2, 4), G1)
p3 = pairing(G2, multiply(G1, 8))


assert p1 == p2, "Fail 1"
assert add(p1, p2) == p3, "Fail 2"

Full error output

    x1, y1 = p1
TypeError: cannot unpack non-iterable bn128_FQ12 object
