* feat: rename Tracer interface to EVMLogger;
minor changes in API
refine api_tracer.go

* feat: add BenchmarkTransactionTrace

* feat: tracer CaptureEnter CaptureExit in evm

* feat: upgrade js tracers with geth upstream

* chore: clean test

* feat: eth/tracers: support for golang tracers + add golang callTracer
cf. https://github.com/ethereum/go-ethereum/pull/23708

* chore: clean testdata json

* fix: change test due to IntrinsicGas is not upgraded

* feat: make native Tracer the default Tracer

* fix: update tracers.New in api

* fix: addr prefix in callTracer
