Adding macros for planing

I would like the weekly planner to display not only the planned calories, but also the corresponding macros (carbohydrates, fats, and protein). This would make it much easier for me to follow a meal plan that aligns with my nutritional goals.

It would also be great if users could set their personal target values (calorie needs, protein intake, etc.) so that these could be taken into account during the planning process.
