test_gas_usage()

Documentation for tests/cancun/eip1153_tstore/test_tstorage.py::test_gas_usage@892e6d1e.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip1153_tstore/test_tstorage.py::test_gas_usage --fork Amsterdam

Test that tstore and tload consume the expected gas.
