feature --gas-report-diff

[fico23]

forge snapshot --diff offers valuable insights into overall gas consumption changes, yet it can sometimes lack granularity due to multiple function calls within tests. Introducing a forge test --gas-report-diff command could provide a more detailed comparison of gas usage at the function(and deployment) level. This feature would complement the existing forge test --gas-report, enabling developers to pinpoint specific changes in gas consumption with greater precision. Such an enhancement would be incredibly useful for optimizing contract efficiency.
