NodeRecorder audioDataCallback update interval

Description

Using Audiokit 5.6.2 the interval at which NodeRecorder's audioDataCallBack is executed is 100ms, instead of the buffer length. In this case recording from iPhone mic, the length is always 4410. I believe this should be much more frequent if I have bufferLength set to .short?

Also most probably related to #2860 which for whatever reason did not fix the problem for AudioDataCallBack in NodeRecorder.

Here is example code:

recorder = try NodeRecorder(
                    node: input,
                    fileDirectoryURL: getDocumentsDirectory().appendingPathComponent("Sounds"),
                    shouldCleanupRecordings: false
                ) 
                
                recorder?.audioDataCallback = { audioData, _ in
                        let length = UInt(audioData.count)
                        print(length)
                }
