Implement searching for North American region

[7bitlyrus]

Implement a search provider that exposes a dict of Games search results for a given region.

Possible Regions: en_US en_CA fr_CA es_LA

Use graph.nintendo.com GraphQL GameGames method to allow games to be searched.

Road map:

• Update Game data class to match/add data returned by API
• Implement search provider
• Write tests

I think we'll have to put this issue on hold until things are re-researched to use Angola search results instead, as Nintendo's GraphQL has had introspection disabled and some parameters renamed. At the very least, it looks like we'll still be able to get the product id thats otherwise hidden in NA:

{
    GetGameByNsuid(nsuid: "70010000036098", locale: "en-US") {
        productCode
    }
}

{
    "data": {
        "GetGameByNsuid": {
            "productCode": "HACPA2NAA"
        }
    }
}
