NoShore: Groundwork for on-the-go offline payments

For years, I've been unable to let go of the vision of creating the simplest payment-interface possible.

I couldn't find the required specialists to outsource some challenging parts of my initial design.

Now, thanks to a discussion with the developer of XmrSigner - plus the interest of someone specialized in FPGA's, I realized that I could create a major part of the functionality and, from there, follow a clear path forward.

Please feel free to review the linked CCS-draft - any workable feedback is welcome!
