Needed to convert to string in headers

[gRittyKitty]

In make_request, the code is:

auth_headers = {
            'Authorization': self.clientKey + ':' + signature.decode('utf8'),
            'X-Auth-Timestamp': timestamp,
            'X-Auth-Nonce': nonce,
            'Content-Type': 'application/json'
}

It threw errors. I was able to get it to run by updating to:

auth_headers = {
            'Authorization': self.clientKey + ':' + signature.decode('utf8'),
            'X-Auth-Timestamp': str(timestamp),
            'X-Auth-Nonce': str(nonce),
            'Content-Type': 'application/json'
        }
