Regorus now defaults to rego v1. `import rego.v1` is no longer needed. Additionally, `future` keywords are automatically imported. See https://www.openpolicyagent.org/docs/latest/v0-upgrade/#changes-to-rego-in-opa-v10 to understand the differences between rego v1 and v0. BREAKING CHANGE: v0 style policies will error out by default. To enable v0 behavior, call engine.set_rego_v0(true) before loading policies.
