Customizable thresholds constants

There are a bunch of constants that govern ultimately how many results are shown:

Lines 31 to 33 in 2d116c4

    
           const thresholdDuration = 5E5; // microseconds 
        
           const minDuration = 1E5; // microseconds 
        
           const minPercentage = 0.6;

IMHO perhaps those constants should be customizable from the CLI, or even better there should just be a "limit" flag to limit the number of files outputted, which by default could be 10 or even the current essentially "auto" limit.

	const thresholdDuration = 5E5; // microseconds
	const minDuration = 1E5; // microseconds
	const minPercentage = 0.6;
