v2.0.0
Add support for MarkdownV2 (8642303), strikethrough and underline (23cef46) and nested formatting (756ba07)
BREAKING CHANGE: html functions do not escape on their own anymore.
Use format.bold(format.escape(input) instead of format.bold(input) whenever you need.
This way you can nest functions like format.bold(format.italic(input)) without escaping the format of the inner one making it useless.
