Add command to get block and/or transaction that deployed a contract

[fvictorio]

There's no JSON-RPC for this, so I guess we should make a binary search using getCode. It would work like this:

• Get the current block number
• Start a binary search getting the code of the contract between 1 and the current block number
• If there's no code in 1 but there is in block number, look at blockNumber/2, repeat.
• Once the block number of the deploy is obtained, get all the transactions of that block, get the recipt, check the contractAddress and see if it matches the given address.
• Use the tx to also obtain the address that deployed it

Notice that this will only work in ganache and in archive nodes.
