Allow MSA token to be changed when fetching packages

[rtm516]

This allows you to pass a token in to fetch betas of apps like Minecraft.

I also load in the ApplicabilityBlob and UpdateId for later checking of if the file. (I generated the classes using https://json2csharp.com/ so may not be perfect)

Also fixed a bug with packages getting mapped incorrectly in 6371b78 And ARM support

Example:

DisplayCatalogHandler dcathandler = DisplayCatalogHandler.ProductionConfig();
await dcathandler.QueryDCATAsync("9nblggh2jhxj", IdentiferType.ProductID, "Bearer WLID1.0=REDACTED");
foreach (PackageInstance package in await dcathandler.GetPackagesForProductAsync("<User>REDACTED</User>"))
{
    Console.WriteLine("{0}\t{1}\t{2}", package.PackageMoniker, package.PackageType, package.PackageUri);
}

Awesome work! Everything seems to work on my end. I'll go ahead and merge it. Thank you for your contribution.
