Update to Sneak atttack itemMacro to use system setting for critical rolls.

[bsleys]

The current macro ignores the 5e system setting for critical rolls, ie maxing critical hit damage dice.
In the itemMacro replace:
const diceMult = args[0].isCritical ? 2: 1;
with:

    const baseDice = Math.ceil(rogueLevels/2);
    let diceMult = 1;
    let maxCritDmg = "";
    if (args[0].isCritical) {
        if ( game.settings.get("dnd5e","criticalDamageMaxDice")) {
            maxCritDmg = ` + ${baseDice * 6}`;
        } else {
            diceMult = 2;
        }
    }

and the return statement with :
return {damageRoll: '${baseDice * diceMult}d6${maxCritDmg}', flavor: "Sneak Attack"};
