test_worst_address_state_warm()

Documentation for tests/zkevm/test_worst_stateful_opcodes.py::test_worst_address_state_warm@64f949d0.

Generate fixtures for these test cases for Prague with:

fill -v tests/zkevm/test_worst_stateful_opcodes.py::test_worst_address_state_warm --fork Prague

Test running a block with as many stateful opcodes doing warm access for an account.
