Update that brings go-ethereum with live tracer support (#1375)
* Update that brings `go-ethereum` with live tracer support This only brings the dependency (will need to wait for a merge + tag of the branch before merging this PR) and the required changes to adapt `DBImpl` to support the new interface. Relates to: - sei-protocol/go-ethereum#15 - #1344 * Added missing instrumentation when state changes in `DBImpl`
