Closes BES-108

BES-108 Automatically allow cheatcodes

In solidity you can get the bytecode of a contract that has not yet been deployed via type(Contract).createionCode

https://docs.soliditylang.org/en/latest/units-and-global-variables.html#type-information

We could make a helper for mocks. It would be used like this:

MockOracle _oracle = MockOracle(deployMock('Oracle', type(MockOracle).creationCode));

The helper will be:

function deployMock(string calldata _label, bytes calldata _creationCode) returns(address _deployed)

Inside the helper we can:

• get the address of the next deployment, using CREATE2
• rewrite its contents using etch. New content - bytecode that is transferred to the helper
• use label to set the name of the contract so that it appears in the foundry logs not just as an address
• return the generated address
