Ability to embed twitch badges and bit emotes

[goldbattle]

This will address issue #359 with the goal of the whole renderer being able to render without internet access.
I am not sure what else is required to do the render, but we have this

// this PR will address
Task<List<ChatBadge>> badgeTask = Task.Run(() => TwitchHelper.GetChatBadges(chatRoot.streamer.id, renderOptions.TempFolder));
// supports offline
Task<List<TwitchEmote>> emoteTask = Task.Run(() => TwitchHelper.GetEmotes(chatRoot.comments, renderOptions.TempFolder, chatRoot.emotes));
// supports offline
Task<List<TwitchEmote>> emoteThirdTask = Task.Run(() => TwitchHelper.GetThirdPartyEmotes(chatRoot.streamer.id, renderOptions.TempFolder, chatRoot.emotes, renderOptions.BttvEmotes, renderOptions.FfzEmotes, renderOptions.StvEmotes));
// this PR will address
Task<List<CheerEmote>> cheerTask = Task.Run(() => TwitchHelper.GetBits(renderOptions.TempFolder, chatRoot.streamer.id.ToString()));
// supports offline
Task<Dictionary<string, SKBitmap>> emojiTask = Task.Run(() => TwitchHelper.GetTwitterEmojis(renderOptions.TempFolder));

Fixes #359

TODOS:

• check backwards compatibility with old JSON files
• use the cached values in the json in the render (right now they are just saved during download)
• add a --offline option for CLI which doesn't do any http requests
• CLI to "upgrade" old chat files with updated emotes / badges...

Maybe create new classes for embedded badges and bits

[ScrubN]

doing that means no dealing with "upgrading" old chat files because the TryGetProperty would return false

[ScrubN]

Thought on it a bit more. Keeping the single class could be nice IF we rename it to something more appropriate like "embeddedData". Still we do not need to deal with "upgrading" old jsons because we can TryGetProperty("embeddedData") else TryGetProperty("emotes").

We can also change --embed-emotes to --embed-data and add a simple find and replace to ConvertFromOldSyntax for backwards compatibility.

Well that wasn't what I had in mind when you said updating chat files. I still stand by my second suggestion as it would make developing less of a headache. I will make a PR to your PR with my suggestion since I am asking for it

PR is live goldbattle#1

Oh looks like I messed up the merge, never resolved a conflict on Github before...

[ScrubN]

Yeah I've messed up every merge I've done on github. I think I found the issue though and left a comment

Fixed the function:

        public static async Task<ChatRoot> ParseJsonStatic(string inputJson)
        {
            ChatRoot chatRoot = new ChatRoot();

            using FileStream fs = new FileStream(inputJson, FileMode.Open, FileAccess.Read);
            using var jsonDocument = JsonDocument.Parse(fs);

            if (jsonDocument.RootElement.TryGetProperty("streamer", out JsonElement streamerJson))
            {
                chatRoot.streamer = streamerJson.Deserialize<Streamer>();
            }

            if (jsonDocument.RootElement.TryGetProperty("video", out JsonElement videoJson))
            {
                if (videoJson.TryGetProperty("start", out _) && videoJson.TryGetProperty("end", out _))
                {
                    chatRoot.video = videoJson.Deserialize<VideoTime>();
                }
            }

            if (jsonDocument.RootElement.TryGetProperty("embeddedData", out JsonElement embedDataJson))
            {
                chatRoot.embeddedData = embedDataJson.Deserialize<EmbeddedData>();
            }
            else if (jsonDocument.RootElement.TryGetProperty("emotes", out JsonElement emotesJson))
            {
                chatRoot.embeddedData = emotesJson.Deserialize<EmbeddedData>();
            }

            if (jsonDocument.RootElement.TryGetProperty("comments", out JsonElement commentsJson))
            {
                chatRoot.comments = commentsJson.Deserialize<List<Comment>>();
            }

            return chatRoot;
        }
