[Android 13] - Bundle#get is deprecated

We use this API to create FixLocation#extras. The logic is simple: there are multiple predefined types, we use bundle.get and check if the returned value is instance of one of the predefined types. If yes, create map entry with the following type, if no, ignore the entry. Code:

        val key = iterator.next()
        when (val value = this.get(key)) {
            is Boolean -> map[key] = Value(value)
            is Byte -> map[key] = Value(value.toLong())
            is Char -> map[key] = Value(value.toString())
            is Double -> map[key] = Value(value)
            is Float -> map[key] = Value(value.toDouble())
            is Int -> map[key] = Value(value.toLong())
            is Long -> map[key] = Value(value)
            is Short -> map[key] = Value(value.toLong())
            is String -> map[key] = Value(value)
            else -> {
                logW(
                    "Unsupported type in location extras",
                    LOG_CATEGORY
                )
            }
        }

Now Bundle#get is deprecated and there is no other way to determine which type has the value by a concrete key. For now we can leave it as-is because deprecation is not removal, but it's very probable that in the future we'll have to face this problem anyway.
Questions:

1. Where is FixLocation#extras used? We use it only to convert back to Location#extras. The whole object is passed to Navigator#updateLocation. Are the extras somehow used there? I see that iOS does not have any extras.
2. Do we need all extras there or just some predefined ones? This way we can use type-safe methods like Bundle#getString if we know the key (and which type the value has).

Start by tracing FixLocation#extras through its conversion back to Location#extras and the Navigator#updateLocation call. Determine whether extras are required and which predefined keys and types are supported; done means an agreed replacement for Bundle#get or a documented reason to retain it.
