* nut-19 sign mint quote * ephemeral key for quote * `mint` adjustments + crypto/nut19.py * wip: mint side working * fix import * post-merge fixups * more fixes * make format * move nut19 to nuts directory * `key` -> `privkey` and `pubkey` * make format * mint_info method for nut-19 support * fix tests imports * fix signature missing positional argument + fix db migration format not correctly escaped + pass in NUT-19 keypair to `request_mint` `request_mint_with_callback` * make format * fix `get_invoice_status` * rename to xx * nutxx -> nut20 * mypy * remove `mint_quote_signature_required` as per spec * wip edits * clean up * fix tests * fix deprecated api tests * fix redis tests * fix cache tests * fix regtest mint external * fix mint regtest * add test without signature * test pubkeys in quotes * wip * add compat --------- Co-authored-by: callebtc <93376500+callebtc@users.noreply.github.com>
