Load different textures for different types of buildings

[MathiasBaumgartinger]

OSM often offers somewhat detailed specifications of buildings which could be used for more diverse rendering of houses/groceries/industrial/...

As of now, the following specifications have been categorized (OSM keys building and amenity):

{   
    "attribute_to_type": { 
        "building": {
            "apartments": "apartments",

                "tent"
            ]
        }
    }
}

Each of the value stands for an individual texture. Should none of these categorizations hold true, we shall use a fallback texture.

The values under yet_to_be_decided could possibly deleted out of the dataset to avoid confusion.

[MathiasBaumgartinger]

Tasks:

• [ ] optimization: load emission, metallic and roughness into one texture to avoid multiple texture reads
• [ ] feature: create a reusable resource for wall-types which has textures for basement, ground, middle and top and allows randomized color adjustments
• [ ] feature: load wished wall-type resource for wished categories
• [ ] feature: extend rendering capabilities by distinguishing between basement, ground, middle, top
• [ ] feature: allow different instances of walls (e.g. category roof will require rendering other than PlainWalls)
