OnsetDetect precision: Third decimal place is always rounded to 0. #506

Hi, when running binary of OnsetDetector, OnsetDetectorLL or CNNOnsetDetector. The third decimal place is always rounded to zero. Anyway to disable it?

The reason is that the resolution of those methods is 100 frames per second, thus when printing with 3 decimals, the last one will always be 0. The reason we're printing 3 decimals is that some other methods use a higher frame rate and hence produce results with a higher precision.

You can change the fmt argument of madmom.io.write_events to change the behaviour.
