change_num_notes: Change in number of notes
In pmcharrison/voicer: Analyzing and Generating Chord Voicings

Checks for changes in the number of notes within a chord transition.

1	change_num_notes(contexts, continuation)

`contexts`	A list of chords corresponding to the first chord in the transition. Each chord should be represented as a numeric vector of MIDI note numbers, without duplicates, sorted in ascending order. The function is vectorized over this argument.
`continuation`	The second chord in the transition, represented as a numeric vector of MIDI note numbers, without duplicates, sorted in ascending order.

An integer vector, vectorized over contexts, providing the absolute change in the number of chord notes between the ith element of contexts and continuation.

This is a voicer feature suitable for passing to the features argument of voice_opt.
