Nonce error when calling spot client

[nontro]

Hi everyone, I am changing my code from a selfmade client to connect API to this library, but everytime I try to get any data I get EAPI: nonce error

`from kraken.spot import SpotClient

client = SpotClient(key="API_KEY", secret="API_PRIVATE_KEY")

print(client.request("POST", "/0/private/Balance"))`
