If more than one channel with the same program color, they should be
added together.
August 22 2023
Midistats improved the calculation of the number of rhythm patterns
in a channel (barChn[chan].rhythmPattern) by allowing for dithering
of note onset. Introduced dithermargin variable in function
stats_noteon(). In function, output_track_summary(), suppressed
notemeanpitch for percussion channel.
