RFC 6979, deterministic signing, Anti-Klepto / Anti-Exfiltration #256

Hello, as title suggests, does the project use RFC 6979 standard to create ECDSA signatures or have any Anti-Klepto / Anti-Exfiltration ability against nonce attacks?

We already use RFC 6979 for signature generation. Anti-Klepto would be nice to have, but will require an additional round of communication via QR codes, which makes UX much more complex. For now I don't have ETA for this feature.
