[Bug] P2PK does not support SIG_ALL

[lescuer97]

if I Create a token with nutstash that is P2PK. It will have SIG_ALL signaled in the inputs.

At this moment the wallet is not signing the outputs and making the swap fail.

@lescuer97 If I understand this correctly, the issue here arises when trying to redeem a token with 'SIG_ALL' proofs.
It seems to me that the problem is in cashu-ts, precisely here: createSwapPayload.
It signs the inputs, but does not verify SIG_ALL conditions. I'll open a PR for it if someone isn't already fixing this.

I'm pretty sure they are correlated because cashu.me is using cashu-ts behind the scenes.

I don't think anyone is working on that right now so I think you are free to do it.

@lescuer97 can you confirm that the issue has been fixed and deployed to production?
