65	/// Generates a URI with an on-chain address, [BOLT 11] invoice and [BOLT 12] offer.
66	///
67	/// The URI allows users to send the payment request allowing the wallet to decide
68	/// which payment method to use. This enables a fallback mechanism: older wallets
69	/// can always pay using the provided on-chain address, while newer wallets will
70	/// typically opt to use the provided BOLT11 invoice or BOLT12 offer.
71	///
72	/// The URI will always include an on-chain address. A BOLT11 invoice will be included
73	/// unless invoice generation fails, while a BOLT12 offer will only be included when
74	/// the node has suitable channels for routing.
75	///
76	/// # Parameters
77	/// - `amount_sats`: The amount to be received, specified in satoshis.
78	/// - `description`: A description or note associated with the payment.
79	///   This message is visible to the payer and can provide context or details about the payment.
80	/// - `expiry_sec`: The expiration time for the payment, specified in seconds.
81	///
82	/// Returns a payable URI that can be used to request and receive a payment of the amount
83	/// given. Failure to generate the on-chain address will result in an error return
84	/// (`Error::WalletOperationFailed`), while failures in invoice or offer generation will
85	/// result in those components being omitted from the URI.
86	///
87	/// The generated URI can then be given to a QR code library.
