WIP: EVM Object Format Reference Tests

[marioevz]

Supersedes #23

Works:

• Prague fork
• Evmone running tests

Doesn't work:

• CREATE3 procedure to deploy the EOF contracts

Some clarification how this should work, maybe it will help:

So in the simplest case init_container can be something like just

code: RETURNCONTRACT{0}(0, 0)
container: assembled_output
data: empty

and then initcode can be

code: CREATE3{0}(0, 0, 0, 0) STOP
container: init_container
data: empty

More complicated case can append data to init_container, by for example getting it from calldata:
init_container:

code: CALLDATACOPY(0, CALLDATASIZE) RETURNCONTRACT{0}(0, CALLDATASIZE)
container: assembled_output
data: empty

initcode:

code: CALLDATACOPY(0, CALLDATASIZE) CREATE3{0}(0, 0, 0, CALLDATASIZE) STOP
container: init_container
data: empty

Thanks for the insights! @spencer-tb is helping me to rebase to main right now, which should fix the issues you mentioned on the discord, and I think it would be very helpful if we start collaborating on the same branch to start improving these python tests.
