在拍摄视频过程中，退后台再回前台，偶发崩溃，遇到过2次
奔溃1： EXC_CRASH (SIGABRT) *** -[AVAssetWriterInput appendSampleBuffer:] Cannot append sample buffer: Must start a session (using -[AVAssetWriter startSessionAtSourceTime:) first
奔溃2： EXC_CRASH (SIGABRT) *** -[AVAssetWriterInputPixelBufferAdaptor appendPixelBuffer:withPresentationTime:] Must start a session (using -[AVAssetWriter startSessionAtSourceTime:) before appending pixel buffers
崩溃之后重新打开APP就无法拍摄，重启手机后又正常了。
怀疑是 didStartWriter 没有正确重置回 false 导致
assetWriter.startSession(atSourceTime: startTimeToUse)没有调用导致的，但还不知道是什么原因。
