fill -v tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_state_gas_sstore.py::test_sstore_multiple_slots --fork Amsterdam

Test multiple zero-to-nonzero SSTOREs each charge state gas.

Each slot written from zero to nonzero independently charges STATE_BYTES_PER_STORAGE_SET * cost_per_state_byte of state gas.
