Add whipser support

[ekudram]

Going to be a multi file change

Noting we cannot return whipsers because no Service allows this anymore
Spam bots have ruined this

I can though allow for forcing commands through wispers as this would reduce spam.

Phase 1 complete
Structure added for whisper Commands

NOTE:
        [Obsolete("Usage of SendWhisper through chat is not possible anymore. Use TwitchLib.Api.Helix.Whispers.SendWhisperAsync() instead.")]
        public void SendWhisper(string username, string message)
        {
            if (!IsConnected || string.IsNullOrEmpty(username))
                return;

            try
            {
                // Rate limiting for whispers (different from regular messages)
                var now = DateTime.Now;
                if (now - _lastMessageTime < _messageDelay)
                {
                    System.Threading.Thread.Sleep(_messageDelay - (now - _lastMessageTime));
                }
                // Obsolete
                _client.SendWhisper(username, message);
                _lastMessageTime = DateTime.Now;
                Logger.Debug($"Sent Twitch whisper to {username}: {message}");
            }
            catch (Exception ex)
            {
                Logger.Error($"Failed to send Twitch whisper: {ex.Message}");
            }
        }

Twitch does not allow sending whispers through chat anymore!

📢 IMPORTANT: Twitch Whispers Not Working? Read This First!

If you're having issues receiving whispers/private messages from viewers, this is almost always a token scope issue.

🛠️ Quick Fix:

1. Regenerate your Twitch token at: https://twitchtokengenerator.com/

2. Click "Custom Scope" (NOT "Bot Chat Token" or quick options)

3. Check ALL THREE boxes:

   [✓] chat:read - Read chat messages
   [✓] whispers:read - Receive whispers ← CRITICAL FOR WHISPERS!
   [✓] chat:edit - Send messages

4. Generate token and paste into the mod settings

5. Reconnect to Twitch

🔍 How to Verify:

• After updating your token:
• Have a viewer send a whisper to your bot with: /w YourBotName test
• Check RimWorld logs (Ctrl+F12 or Ludeon/RimWorld/Player.log)
• Look for messages containing "WHISPER" or "TWITCH WHISPER"

📝 Common Symptoms:

✅ Bot receives public chat messages
❌ Bot does NOT receive whispers/private messages
✅ Bot can send public messages
❌ Bot cannot send whispers (deprecated by Twitch anyway)

🤔 Why This Happens:

Twitch requires specific permissions (scopes) for different functions. The default "Bot Chat Token" often doesn't include whispers:read scope, which is required to receive whispers.

💡 Pro Tips:

• Use a separate bot account if possible
• Bookmark this page for token regeneration
• Consider using public chat instead of whispers (works for 95% of users)
• Check token length - should be ~30-40 characters including "oauth:"

❓ Still Having Issues?

If you've followed these steps and whispers still don't work:
Copy your RimWorld log (Player.log file)
Send a test whisper to your bot

Create a new issue with:

• Your mod version
• RimWorld version
• Relevant log excerpts (look for "WHISPER" or "Twitch")
• Confirmation you used all three scopes

⚠️ Known Limitations:

• Twitch Has phase out bot-sent whispers (receiving still works)
• Some users need phone verification on Twitch for whispers
• Rate limits apply (40 whispers/day per user pair)
