As Zeromorph is not a default PCS, we are postponing its maintenance in Solidity and close it for now. Branch will still exist |

This work is motivated by argumentcomputer/arecibo#145, which improves previous one and finally adds completed Zeromorph PCS to Arecibo.
Zeromorph requires performing some computations over G2 elements within Bn256 curve (addition / scalar multiplication) and this PR actually adds sketch of the library that can be further utilised by higher-level Zeromorph step library and e2e contract eventually.
Currently only addition of G2 elements is supported and scalar multiplication should be delivered in subsequent PRs.
