Organising the StarknetWrapper was not a goal for this PR, because there is not so much to organise. But the plan is to have one object like StarknetWrapper that holds references to state, blocks, transactions, accounts. Then with all the logic coming to this class it will become larger so the idea is to split the implementation of this StarknetWrapper like object to multiple files, each file will be responsible for a group of "service" methods. Then those methods will interact with the properties of the StarknetWrapper like object. The goal for each method is to combine set of invocations to the members of StarknetWrapper, so we can keep each "service" method not so big.

After running cargo run, there is a warning for [dead_code] for the state member of Starknet struct. This happens, because when constructing Starknet object, the state member is being assigned to the object after all of the changes to it and in this PR there are no interactions with the state property of Starknet struct in any of the other methods (currently there are 2 - new, get_predeployed_accounts)
