Firestore: more flexible serialization

I am having some issues trying to get Firestore API to convert between StringValue and DDD value objects which are fully convertible from/to string. Let me give an example:

[FirestoreData]
public class UserAccount
{
     [FirestoreProperty]
     public Email EmailAddress { get; set; }
}
public class Email 
{ 
     // Email has a TypeConverter implementation that allow full conversion from/to string
     // Email also has implicit operators to allow direct conversion from/to string
}

When calling snapshot.ConvertTo<UserAccount>(), ValueDeserializer fails with System.ArgumentException: 'Unable to convert value type StringValue to Email'.

It seems ValueDeserializer ignores type converters and implicit operators completely.

PR #2734 is the first pass of the “real” version of this.

Great! Thank you very much. I will give it a try next week.
