Pimlico based changes for examples/4337-gas-metering

[remedcu]

This PR intends to use the latest EntryPoint v0.7 along with the new paymaster from Pimlico. Fixes #294

Current Blockers

• Pimlico Paymasters are still having some problems during execution and estimation.
• preVerificationGas related estimations are still off by a bit.

The Pimlico team have been informed regarding the same at the time of writing this issue.

Changes completed/in-progress

• Using base-sepolia as well (sepolia sometimes has a high gas cost)
• Using new signing struct with the latest 4337 Safe Module
• Update of permissionless package

Things remaining (and nice to do)

• Checking compatibility with the Pimlico Gas Metering Task
• Creating the Table with Pimlico-based (with/out paymaster) gas usage of Safe 4337 Module (using EntryPoint v0.7)
• Possible refactoring of the code a bit more for easier future changes and comprehension.
