I don't see any issue. It looks great. One thing though, we updated reth and revm so can you please rebase.
re additonal allocations / performance: I don't think that this changes the pictrure in any way
- we were already instrumenting step
- this adds call/call_end instrumentation that runs very rarely
- we were already allocating hashmap for each slot and here it allocates a tiny bit of data that is much smaller than that (the order is just the number of internal calls)
…t_amount, created_contracts, destructed_contracts. Add test for evm inspector.

This should check if contract was already destroyed and return if yes. Selfdestruct can be called multiple times in one tx.

This would be incorrect if call fails.
## 📝 Summary Added support for SELFBALANCE, BALANCE, CALL, CREATE, and SELFDESTRUCT op-codes in UsedStateEVMInspector. New test cases for evm inspector have been added. ## 💡 Motivation and Context Related discussion in #58. For opcodes like EXTCODECOPY, EXTCODEHASH, and EXTCODESIZE, I thought we could add them in the future with a concrete use case, so that we can properly design the datastruct for it. --- ## ✅ I have completed the following steps: * [x] Run `make lint` * [x] Run `make test` * [x] Added tests (if applicable)
