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