There is a security issue found in github.com/btcsuite/btcd that we don't care about (we're only using 256k1 implementation), but GitHub complains about it. We could update to github.com/btcsuite/btcd/btcec/v2, but it's now just a thin wrapper over github.com/decred/dcrd/dcrec/secp256k1/v4, so we better use it directly.
