Not compatible with newer solidity versions

[atulr-crypto]

The repository is not compatible to integrate with newer versions of the solidity.
for instance, swap-router-contracts/contracts/interfaces/ISwapRouter02.sol interface includes interface IApproveAndCall has locked compiler version to =0.7.6.

A third party contract with new solidity compiler that wants to integrate ISwapRouter interface will give compile error.
Error (5333): Source file requires different compiler version
