Can I just say I love this project very much! Thank you for creating it. I'm migrating to it and rewriting almost all my app to be more coco-first. These are just suggestions of things where I've gotten stuck and been forced to rethink my usage of the library. 1. Can we add some status field to `SendHistoryEntry` & `ReceiveHistoryEntry`? It seems like I need to use `proofService` otherwise but I think that's a private field, I just got a bit stuck on this. 2. Maybe add `token` to `ReceiveHistoryEntry`? I know it's not super needed but its nice to show the user which token the redemption is for. 3. Could we add some field to HistoryEntry for npc receives from `coco-cashu-plugin-npc` so that I can know thats where the payment came from? 4. I found `cashu-kym` pretty useful to and I think it might belong in `coco`. 5. I'm having a weird thing happen where the state goes from PENDING->ISSUED->PAID->ISSUED. It seems to incorrectly revert to ISSUED (when minting). It could be some poor configuration on my side but I attached a video to help demonstrate whats going on.
