test_worst_calldatasize()

Documentation for tests/zkevm/test_worst_compute.py::test_worst_calldatasize@64f949d0.

Generate fixtures for these test cases for Prague with:

fill -v tests/zkevm/test_worst_compute.py::test_worst_calldatasize --fork Prague

Test running a block with as many CALLDATASIZE as possible.
