Connect to Twitch chat

Started rewriting BlushyFace.Twitch.Chat into BlushyFace.Twitch.Chat.V2 because while v1 is a rewrite ported from my .NET FX version I wasn’t totally happy with it and decided to just rewrite it in it’s entirely. This is a work in progress but the basic client is fully functional. The client features are based on what I need so if you have suggestions what you would like me to add let me know with a comment below or join our discord.

The example shows how to create multiple clients, client is a user that is logged in to chat and able to receive & send chat messages while client2 is anonymous and can only receive chat messages. Requires .NET Core 3.x to run.

Features
– connect to twitch chat
– support for various capabilities
– send & receive messages / whispers
– reconnect on disconnect
– subscribe to various events

Connected clients can be identified by the login name.
In this instance there are 2 clients, 1 named blushyface and one named justinfan12345 both in the channel #blushyfacebot

// edit, seems the used WP plugin to highlight code eats greater / lower characters so the examples might not work properly.

For example -> List<string> Channels = new List<string>(); becomes List Channels = new List(); so change where needed until I have a better plugin that does not do that (?).
