Tracing with package runtime/trace shows the scanner.start and worker.run goroutines block frequently on the workerCh channel. Add buffering to workerCH to reduce blocking and increase concurrency. When scanning a 4 GB ZNG file containing Zeek logs, this yields a 1.1X speedup on my 10-core machine.
