[Scripts] Deploy implementations direct

[tomhirst]

We have a client request to deploy a launchpad contract with a vanity address, but we can't do this with our existing factory deployment flow:

The salt for the vanity address needs to be pre-computed with forge create2. However, when this salt is passed to createContractDeterministic it's re-hashed with msg.sender and block.chainId. Meaning, the salt will not be the same and the vanity address with not be achieved:

magicdrop/contracts/factory/MagicDropCloneFactory.sol

Line 122 in cd314bc

bytes32 _salt = keccak256(abi.encode(salt, block.chainid, msg.sender));

These scripts directly deploy ERC721CM (non-initializable variant) directly using the pre-computed salt to achieve the vanity address via CREATE2.

Cool with however you want to approach this. The smallest impact way I saw to accomplish this is to add a nonce to this line and take the parameter. Then you can grind CREATE2 addresses all day
