LayerChangeFlags should also accept Record<string, boolean>

[jeffpeck10x]

i.e.

updateTriggersChanged: boolean | string | Record<string, boolean> | null;

My workaround at the moment is to do this:

   const { updateTriggersChanged } = changeFlags as {
      updateTriggersChanged: false | Record<string, boolean>;
    };

  if (updateTriggersChanged && updateTriggersChanged.theAccessor) {
    ...
  }
