Thanks @marioevz this looks very good to me.

Love the addition to the fixture _info field:

As a follow-up PR, should we diff the expected opcode count (as defined by the bytecode) with that from evmone-t8n if different during filling? Or did you consider that going too far?

This is extremely helpful in some situations especially that it is being added to the fixtures info field. For benchmarks esp. regarding gas pricing it would be super helpful to include this in the fixtures by default (so also on the releases). Could this be done?
