Daide Extension for responding as potential/indeterminate acceptance of an offer

[jnusrath]

What functionality will your new tokens add?
A new token might be added for sending potential/indeterminate acceptance responses to an order proposal.

Describe the precise changes you'd like

• Along with using the existing Daide token, we propose a new token PAC for sending responses as potential/indeterminate acceptance of arrangement.
• Daide clauses for this might be “SND (power power …) (PAC (PRP(arrangement)))”
• Example - if a power sending Russia a potential acceptance of the order proposal that Russia sent to them earlier, the Daide clause might be “ SND (RUS)(PAC(PRP(XDO((RUS AMY MOS) SUP (GER AMY BER))))) ) “

Additional context
For the negotiation between agents, we are proposing Daide extension.
