This is a final sweep to match the current BOLT12 text:
1563d13999d342680140c693de0b9d65aa522372 ("More bolt12 test vectors.")
Only two code changes, to change the order of checks to match the bolt,
and to give a warning on decode if a path is empty.

* A writer of an offer:

* - MUST NOT set any TLV fields outside the inclusive ranges: 1 to 79 and 1000000000 to 1999999999.
|
|
* - if the chain for the invoice is not solely bitcoin:
|
|
* - MUST specify `offer_chains` the offer is valid for.
|
|
* - otherwise:
|
|
* - MAY omit `offer_chains`, implying that bitcoin is only chain.
|
|
* - if a specific minimum `offer_amount` is required for successful payment:
|
|
* - MUST set `offer_amount` to the amount expected (per item).
|
|
* - if the currency for `offer_amount` is that of all entries in `chains`:
|
|
* - MUST specify `amount` in multiples of the minimum lightning-payable unit
|
|
* (e.g. milli-satoshis for bitcoin).
|
|
* - otherwise:
|
|
* - MUST specify `offer_currency` `iso4217` as an ISO 4712 three-letter code.
|
|
* - MUST specify `offer_amount` in the currency unit adjusted by the ISO 4712
|
|
* exponent (e.g. USD cents).

|
* - MUST set `offer_description` to a complete description of the purpose
|

* of the payment.

* - otherwise:

* - MUST NOT set `offer_amount`

|
* - MUST NOT set `offer_currency`
|

* - MAY set `offer_description`
|
|
* - MAY set `offer_metadata` for its own use.
|
|
* - if it supports bolt12 offer features:
|
|
* - MUST set `offer_features`.`features` to the bitmap of bolt12 features.
|
|
* - if the offer expires:
|
|
* - MUST set `offer_absolute_expiry` `seconds_from_epoch` to the number of seconds
|
|
* after midnight 1 January 1970, UTC that invoice_request should not be
|
|
* attempted.
|
|
* - if it is connected only by private channels:
|
|
* - MUST include `offer_paths` containing one or more paths to the node from
|
|
* publicly reachable nodes.
|
|
* - otherwise:
|
|
* - MAY include `offer_paths`.
|
|
* - if it includes `offer_paths`:
|
|
* - SHOULD ignore any invoice_request which does not use the path.
|
|
* - MAY set `offer_issuer_id`.
|
|
* - otherwise:
|
|
* - MUST set `offer_issuer_id` to the node's public key to request the invoice from.
|
|
* - if it sets `offer_issuer`:
|
|
* - SHOULD set it to identify the issuer of the invoice clearly.
|
|
* - if it includes a domain name:

* - SHOULD begin it with either user@domain or domain
|

* - MAY follow with a space and more text
