[accumulator]

This happens when a BIP21 contains an explicit amount=0.

Not sure how to handle

1. consider as invalid BIP21 uri
2. consider as 'amountless' invoice

[SomberNight]

Or, option (3): treat it as wanting to create a 0-value output. That would make sense for e.g. OP_RETURN, though I guess bip21 cannot be used for scripts that don't have a corresponding address.

2. consider as 'amountless' invoice

There is an explicit amount, so I don't think this is correct.

I would prefer (1) or (3).
