Add quality checks in the NodeJS package

Problem

Currently, we don't check what is sent in the nutrition, whereas on the website we have multiple checks.

Proposed solution

Add checks that can return warnings

• Ensure the relation between kJ / kCal is correct
• Energy should not exceed 3800 kJ (?)
• Generally speaking, all items shouldn't exceed 100g if it's per 100g (e.g. Fat, Carbohydrates, ...)
• Saturated fat should not exceed fat
• Sugars should not exceed carbohydrates
• Compute sodium / salt
