Updated to Bot API 9.3.

More useful functionality for Hamilton::Storage added.

Better Hamilton::Context with non-Nil Hamilton::Storage as inner storage of Hamilton::Any (mutable version of JSON::Any)

• Fixed bug with serialization of Arrays or Unions with Nil
• Proper creation of Hamilton:Types:: with .new from arguments (not JSON)

Hamilton is now able to handle updates concurrently with -Dasync flag on. More about usage in the guide.

Fixed bug with ApiResult.

Package provides wrapper for Telegram Bot API:

• Types can be accessed from Hamilton::Types module
• API methods are methods in Hamilton::Api class
• Hamilton::Bot retrieves updates from Telegram with long pooling and handles them with specified handlers:
  • Hamilton::LogHandler logs update type and time consumed to handle it
  • Hamilton::CmdHandler handles most popular types of updates
  • Hamilton::Handler module may be used to create custom handlers
