New constructor topicsdb.NewWithThreadPool() makes the same topicsdb.Index that by legacy topicsdb.New() but wrapped with threads-in-use limiter.
It prevents the 'thread exhaustion' fail but leads to not full CPU/Mem utilization, i.e. more 'eth_getLogs' calls will be rejected by timeout. Const topicsdb.GoroutinesPerThread is for tuning.
