Add infrastructure support for suggesting score.

[toebes]

Create a new routine
genScoreRange() : number[] {
}

First number is the suggested score, Next two numbers are the low and high for the range.

[toebes]

Once this is done create issues to add genScoreRange() to all the ciphers.

[toebes]

There are three things that each cipher needs to do:

1. Add a routine like

/**
 * Generate the recommended score and score ranges for a cipher
 * @returns Computed score ranges for the cipher
 */
public genScoreRange(): suggestedData {
   return { suggested: 0, min: 0, max: 0 }
}

which returns the suggested score and an min/max range for what the score should fall into. Note that if max <= min then the range is ignored and only a suggested score is given.
2. Add a routine like

/**
 * Determine what to tell the user about how the score has been computed
 * @param suggesteddata Data calculated for the score range
 * @returns HTML String to display in the suggested question dialog
 */
public genSamplePointsText(suggesteddata: suggestedData): string {
   return `<p>We suggest you try a score of ${suggesteddata.suggested}</p>`
}

which returns an HTML string that is posted directly into the dialog. Note that the suggestedData from the genScoreRange() routine is passed into this routine. If there is additional information you need passed in (such as is done for the Aristocrat one) then there is a private field in the suggestedData structure that can hold any.
3. In the cmdButtons, add this.questionButton,this.pointsButton, before this.guidanceButton, so that the buttons appear on the UI.

    public cmdButtons: JTButtonItem[] = [
        this.saveButton,
        this.undocmdButton,
        this.redocmdButton,
        this.questionButton,
        this.pointsButton,
        this.guidanceButton,
        { title: 'Reset', color: 'warning', id: 'reset' },
    ];
