Feature Request

Description: In addition to retrieving the app's version number, add functionality to retrieve the app's release notes.

I've downloaded the source and added support for this to Android and iOS but I don't develop UWP apps. Here's what I came up with that works well with our app's release notes formatting:

Interface addition:

Task<string> GetLatestReleaseNotes();

Android release notes retrieval:

var content = responseMsg.Content == null ? null : await responseMsg.Content.ReadAsStringAsync();

var versionMatch = Regex.Match(content, "<div[^>]*>Current Version</div><span[^>]*><div[^>]*><span[^>]*>(.*?)<").Groups[1];

if (versionMatch.Success)
{
	version = versionMatch.Value.Trim();
}

var releaseNotesMatch = Regex.Match(content, "<h2[^>]*>What&#39;s New</h2>.*<div.*itemprop=\"description\"[^>]*><span([^>]*>)(.+?)</span>").Groups[2];

if (releaseNotesMatch.Success)
{
	var newLines = Environment.NewLine + Environment.NewLine;
	releaseNotes = releaseNotesMatch.Value.Trim().Replace("<br><br>", newLines).Replace("<br>", newLines);
}

iOS release notes retrieval:

var http = new HttpClient();
var response = await http.GetAsync($"http://itunes.apple.com/lookup?bundleId={_bundleIdentifier}");
var content = response.Content == null ? null : await response.Content.ReadAsStringAsync();
var appLookup = JsonValue.Parse(content);

var newLines = Environment.NewLine + Environment.NewLine;

return new App
{
	Version = appLookup["results"][0]["version"],
	Url = appLookup["results"][0]["trackViewUrl"],
	// Convert single line returns to double line returns without changing existing double line returns
	ReleaseNotes = ((string)(appLookup["results"][0]["releaseNotes"])).Replace("\n\n", "<br>").Replace("\n", newLines).Replace("<br>", newLines)
};

I want this as well.

Any progress here? I'll create another nuget if we stuck here.
