Telegram Bot API, Bot API 2.x, Bot API 3.5

• Proxy: +
• Array and Map as a data source (.call, .callJson, .apimethod): +
• Analytics: tgb-pl-botanio
• Added: tgBot.apisendMethod => error.retryAfter
• Added: sendMediaGroup (doesn't support "attach://")

- All methods in the Bot API are case-insensitive (method: .call, .callJson)

- message:                                             buffer, stream, string
- location|venue|contact:                              buffer, string
- photo|audio|voice|video|document|sticker|video_note: buffer, stream, file_id, path, url
- certificate:                                         buffer, stream, path, url

Goals:

1. High stability;
2. Low memory usage;
3. Maximum performance;
4. Flexibility.
