Allow setting an HRN in invoice_requests built by pay_for_offer
If a user did their own BIP 353 lookup to fetch an offer from a human readable name, we still want them to be able to use `ChannelManager::pay_for_offer`. Because BIP 353 offer payments require that the `invoice_request` include the human readable name, we need to add an argument to set the `invoice_request` HRN to `pay_for_offer`, which we do here.
