Fix cycle sim cache keys

[xpdota]

Currently, only a single key is used:

        const setSpeed = set.isStatRelevant('spellspeed') ? set.computedStats.spellspeed : set.computedStats.skillspeed;
        if (setSpeed !== this.cachedSpeed) {
            this.cachedCycleProcessors = this.generateRotations(set);
            this.cachedSpeed = setSpeed;
        }

However, this fails in two circumstances:

• Whether to auto-attack or not is determined not just by the explicit sestting, but also by whether you have a weapon equipped or not
• PLD/RDM should not be treated as a single speed value

Instead, consider using an array of relevant data as the cache key.
