Error on eddsa.sign()

[calvbore]

Would keep getting this error when trying to use the sign function: TypeError: "list" argument must be an Array of Buffers

Quick fix for the error by modifying lines 57 & 58 of eddsa.js

function now looks like:

function sign(prv, msg) {
    const h1 = createBlakeHash("blake512").update(prv).digest();
    const sBuff = pruneBuffer(h1.slice(0,32));
    const s = utils.leBuff2int(sBuff);
    const A = babyJub.mulPointEscalar(babyJub.Base8, Scalar.shr(s, 3));

    const rBuff = createBlakeHash("blake512").update(Buffer.concat([h1.slice(32,64), msg])).digest();
    let r = utils.leBuff2int(rBuff);
    const Fr = new F1Field(babyJub.subOrder);
    r = Fr.e(r);
    const R8 = babyJub.mulPointEscalar(babyJub.Base8, r);
    const R8p = Buffer.from(babyJub.packPoint(R8)); //CHANGED from: const R8p = babyJub.packPoint(R8);
    const Ap = Buffer.from(babyJub.packPoint(A));   //CHANGED from: const Ap = babyJub.packPoint(A);
    const hmBuff = pedersenHash(Buffer.concat([R8p, Ap, msg]));
    const hm = utils.leBuff2int(hmBuff);
    const S = Fr.add(r , Fr.mul(hm, s));
    return {
        R8: R8,
        S: S
    };
}

Not sure if this is a suitable fix to merge but it has worked for my needs so far.
