/**
* Converter used by `withConverter()` to transform user objects of type
* `AppModelType` into Firestore data of type `DbModelType`.
*
* Using the converter allows you to specify generic type arguments when
* storing and retrieving objects from Firestore.
*
* In this context, an "AppModel" is a class that is used in an application to
* package together related information and functionality. Such a class could,
* for example, have properties with complex, nested data types, properties used
* for memoization, properties of types not supported by Firestore (such as
* `symbol` and `bigint`), and helper functions that perform compound
* operations. Such classes are not suitable and/or possible to store into a
* Firestore database. Instead, instances of such classes need to be converted
* to "plain old JavaScript objects" (POJOs) with exclusively primitive
* properties, potentially nested inside other POJOs or arrays of POJOs. In this
* context, this type is referred to as the "DbModel" and would be an object
* suitable for persisting into Firestore. For convenience, applications can
* implement `FirestoreDataConverter` and register the converter with Firestore
* objects, such as `DocumentReference` or `Query`, to automatically convert
* `AppModel` to `DbModel` when storing into Firestore, and convert `DbModel`
* to `AppModel` when retrieving from Firestore.
*
* @example
*
* Simple Example
*
* ```typescript
* const numberConverter = {
* toFirestore(value: WithFieldValue<number>) {
* return { value };
* },
* fromFirestore(snapshot: QueryDocumentSnapshot, options: SnapshotOptions) {
* return snapshot.data(options).value as number;
* }
* };
*
* async function simpleDemo(db: Firestore): Promise<void> {
* const documentRef = doc(db, 'values/value123').withConverter(numberConverter);
*
* // converters are used with `setDoc`, `addDoc`, and `getDoc`
* await setDoc(documentRef, 42);
* const snapshot1 = await getDoc(documentRef);
* assertEqual(snapshot1.data(), 42);
*
* // converters are not used when writing data with `updateDoc`
* await updateDoc(documentRef, { value: 999 });
* const snapshot2 = await getDoc(documentRef);
* assertEqual(snapshot2.data(), 999);
* }
* ```
*
* Advanced Example
*
* ```typescript
* // The Post class is a model that is used by our application.
* // This class may have properties and methods that are specific
* // to our application execution, which do not need to be persisted
* // to Firestore.
* class Post {
* constructor(
