Proposal: Websocket Payment Tracking
This PR attempts to provide an easy and reliable way to get payment notifications, through a Websocket subscription. It's an alternative to block confirmation/pending/balance checks, and supports single-use accounts and block hand-off.
Preliminary documentation: https://github.com/cryptocode/notes/wiki/Websocket-Payment-Tracking
- [x] It adds ledger functionality similar to https://github.com/nanocurrency/nano-node/pull/3022 - will move this PR to those ledger functions once they're merged.
I also agree it would be nice if wallets supported the "blob" qr code for sending from an account, for instance if the customer needs a refund can get it from the account (assuming the funds are pocketed first), and also for payouts from things like arcade machine.
