Add a way to avoid chords with "X"

[Soy-Asher]

When using the sized-chordlib as in the example:

#place(right, dx: -1em, {
    set align(left)
    // Make all text in chord graph bold
    show text: strong
    // List of used chords there
    sized-chordlib(heading-level: 2, width: 130pt, tuning: "A3 D4 F#4 B3", true-bass: false)

})

It would be great to have an option to select the full chords. By example:

C#m as "4 3 2 2" instead of "X 3 2 2"
