Inconsistencies in deviation object format result in deserialization error

[AlexCSDev]

Hello, while using DeviantArtFs.Api.Browse.PageNewestAsync method I have noticed that there is an inconsisency in returned deviation objects which results in the following error:

FSharp.Json.JsonDeserializationError: JSON Path: results[117].tier.stats. Failed to parse record from JSON that is not object.

Here is the problematic tier object in question:

            "tier": {
                "state": "active",
                "is_user_subscribed": false,
                "can_user_subscribe": true,
                "subproductid": 569102470,
                "dollar_price": "5.00",
                "settings": {
                    "access_settings": "all"
                },
                "stats": [],
                "benefits": [
                    "Welcome Gift!",
                    "Early Access to New Work",
                    "Over 2k Resolution Images"
                ]
            },

As you can see, despite documentation mentioning it can only be an object, for some reason they are returning array for stats and I guess that's why deserialization error is happening. I have also tested this with /deviation/#GUID# endpoint and it returns the same out of spec object, so this seems to be an issue in all of their api endpoints which return deviation object.

I'm not sure if you can do something about that, but I thought it's worth letting you know about this issue.

Whatever serializer DeviantArt uses must (at least sometimes) render empty objects {} as empty arrays [] - I'm guessing whatever langauge they use on the backend doesn't distinguish between those two. I remember having an issue like that before.

I might just remove tier.stats from the model and add a note about it, unless you (or someone else) needs to use that for something.

I don't particularly need that, so feel free to remove it if that's the easiest way of dealing with that.

Should be fixed in https://www.nuget.org/packages/DeviantArtFs/9.1.1
