Hunger saturation system for Bedrock

Currently it takes way too long to heal in Bedrock edition; implementing this mechanic will not also make it more accesible for players with lower mechanical level to fight against difficult mobs like the Wither but also will introduce meaning to what food are you eating, incresing variety in gameplays and reasoning to go out for certain rare foods. It should be implemented smiliar if not equally as it is implemented in Java edition: the more saturation you have, the more you heal semi-instantly.
