Please, make Chattable interface more friendly for the library clients:

// Chattable is any config type that can be sent.
type Chattable interface {
	Values() (url.Values, error)
	Method() string
}

Currently, Telegram bot has many methods that are not implemented in your library.

Found few cyclical dependencies in the source code.

Example:
features/announcements/index.js -> exports ANNOUNCEMENTS_ROUTES and also imports AnnouncementsStore from features/announcements/store.js

features/announcements/store.js -> imports ANNOUNCEMENTS_ROUTES from index.js resulting in cyclical dependency.

There are few more modules where the same issue is present.
