Support contract ABIs

[tkstanczak]

CONTRACT ABI
Contract ABI is a representation of a StarkNet contract. It is formatted as a JSON and describes the functions and the structs of the contracts.

You can get it via –

starknet-compile contract.cairo
--output contract_compiled.json
--abi contract_abi.json
or by executing get_code in the StarkNet CLI.
