API & Action Locking

• Works with Core rounds: switching SCS rounds will update the default combat tracker
• Fix app not appearing in the right position when the canvas is disabled or no scene is activated
• Added Action Locking which restricts actions based on the current phase. Only works for known phases (Move, Attacks, Spells). Feel free to make suggestions on my discord server for more phases that could have Action Locking.
• Switched to esmodules and opened up some functions as an API
