Add discussion about the presence of a free-option in multi-party protocols.
Why
@jonjove highlighted the presence of a free-option in payment channel protocols. This is not unique to Starlight and plagues many multi-party protocols, especially payment channel protocols.
Given that Starlight is a single-asset payment channel protocol at this time the ability to exploit this is limited to free-options with off-chain value that is being exchanged with value captured in the payment channel.
