PROJECT: Adapt LetheKit for SeedSigner

[shannona]

LetheKit v0 is an open source DIY hardware box with offline cryptographic tools. It can use dice for entropy, import seeds in a variety formats, and exports derived keys using UR-based QR codes.

However, it can't support crypto-request QRs, or sign transactions as it does not have a camera.

SeedSigner is another open source DIY device that does have a camera and a better display but it does not support UR QRs.

The goal would be to evaluate if we can submit patches to @SeedSigner to add all the UR functionality that LetheKit has, and if not, port the LetheKit code to that hardware as an alternative to the seedsigner code base.

Sub-projects could be to understand requirements (for instance, LetheKit forgets when powered off, I'm not sure with seedsigner) and use cases, evaluate their code, update the existing LetheKit v0 code for recent UR features, write docs, create a video tutorial, update the LetheKit web page, etc.

@ksedgwic or @gorazdko, fomer leads on LetheKit project might be persuaded to be mentors.

Whoop, this is ENTIRELY encapsulated in #89 already, no reason to repeat it. Closing.
