Move BOLT11 payments API to Bolt11PaymentsHandler

@@ -11,7 +11,7 @@ A ready-to-go Lightning node library built using [LDK][ldk] and [BDK][bdk].
 LDK Node is a self-custodial Lightning node in library form. Its central goal is to provide a small, simple, and straightforward interface that enables users to easily set up and run a Lightning node with an integrated on-chain wallet. While minimalism is at its core, LDK Node aims to be sufficiently modular and configurable to be useful for a variety of use cases.
 
 ## Getting Started
-The primary abstraction of the library is the [`Node`][api_docs_node], which can be retrieved by setting up and configuring a [`Builder`][api_docs_builder] to your liking and calling one of the `build` methods. `Node` can then be controlled via commands such as `start`, `stop`, `connect_open_channel`, `send_payment`, etc.
