test_mcopy_on_empty_memory()

Documentation for tests/cancun/eip5656_mcopy/test_mcopy.py::test_mcopy_on_empty_memory@88e9fb8f.

Generate fixtures for these test cases for Osaka with:

fill -v tests/cancun/eip5656_mcopy/test_mcopy.py::test_mcopy_on_empty_memory --fork Osaka

Perform MCOPY operations on an empty memory, using different offsets and lengths.
