Pull Request Overview

This PR adds the backend functionality for the recipe recommendation. It includes all new API calls necessary and the deserialization of the JSON.

Main Changes

Create RecipeInstructionResponseAPI.kt class: Represents the response of possible recipes that can be made given a list of ingredients from Spoonacular.
Modify SpoonacularAPI.kt class: Added two functions, one that fetches the steps/instructions to make a recipe and another that handles all the calls necessary to create complete recipes with steps (two API calls) given a list of strings.
Create RecipeInstructions.kt class: A card that displays a single step for a recipe.
Modify RecipeRecommendationMoreDetailScreen.kt class: Shows a loading animation while it fetches data from the API.

Just for reference what you see in the video made 12 API calls :

Integrating the barcode and the recipe recommendation to create a coherent feature.

A few things had to be removed due to constraints from the API. For example, the calories and nutritional facts were removed because it would require making at least two more calls per recipe and creating new deserialization and data classes.
Also, due to the high number of API calls made by this class, the first and most expensive call that returns a list of possible recipes given a list of strings has been hardcoded to return only one value for now. The other calls are made as they normally would be, so please avoid making too many calls.
Also waiting on the fix from #321 to merge

The PR is about 500 lines, I also refactored JSON variables used in tests to be in their own folder to make things more readable causing the addition metric to be this high

@medwardson The best way to test the functionality is to set the start navigation in MainActivity from this:

        val startDestination = if (authentication.isAuthenticated()) Route.Home else Route.Register

to this :

        val startDestination = if (authentication.isAuthenticated()) Route.RecipeRecFlow else Route.RecipeRecFlow
