Deploy to stable addresses using CREATE2

Current state of work

• Using classic ethers deployments, CREATE2 strategies is not supported and would need manual implementation of the deployment which is too complex and error prone (such tasks should ideally be left to existing frameworks or tools).
• Hardhat Ignition does support CREATE2 and seems to be the way forward for CREATE2 deployments with hardhat.
  But Hardhat ignition is not not fully stable yet (as of now we are using v0.15.5). After first tests, an issue was found that would lead to an exception during verification of the code (RangeError: Maximum call stack size exceeded during verification on deployment NomicFoundation/hardhat-ignition#770) and that was fixed. Now i've stumbled upon a bug where the gas price is not correct for L2s (hardhat ignition shows too high gas fees for L2s NomicFoundation/hardhat-ignition#724) which lead to a depletion of testing matics. Waiting for a response on the state of that bug.
• Right now it seems that ignition is not as stable as we want it to be and we should therefor postpone the CREATE2 deployments for some time.
• Pending task: confirm that ignition correctly verifies the code that was deployed (could not be confirmed so far due to the bugs mentioned above)
• current implementation: the script ignition/modules/GifCore.ts contains a full deployment of the GifCore (like using GifDeployer). Deployment of services needs to be implemented once the decision to go forward with ignition has been done.
