Adding swap v2 to generic router

[SocksNFlops]

Merge pending

• v2 core being set to public

Changes:

Adding V2 integration into GenericRouter

• Swap
• Add
• Remove

How bytes data is encoded:

bytes memory data = abi.encodePacked(V2, plBps, feeBps);

No matter the representation, the first 8 bits will be used to encode the version.

How bytes data is decoded for V1:

        assembly {
            version := mload(add(data, 0x01))
        }

How bytes data is decoded for V2

function decodeData(bytes memory data) internal pure returns (uint8 version, uint16 plBps, uint16 feeBps) {
        assembly {
            version := mload(add(data, 0x01))
            plBps := mload(add(data, 0x03))
            feeBps := mload(add(data, 0x05))
        }
    }

• Added V2 support to SWAP and USDM_SWAP operations

Testing:

• Unit tests for Swap_V2
• Unit tests for Add Liquidity V2
• Unit tests for Remove Liquidity V2

forge coverage is failing because of a foundry-issue where forge coverage recompiles the lib-dependencies with different optimizations than they were pre-computed with, whereas forge test and forge create does not.
