Cloudflare IP fields are set as string instead of IP

When Cloudflare logs are ingested through the Lambda function, the ClientIP, EdgeServerIP, and OriginIP fields are brought in as a string instead of an IP address. This means that the field cannot be queried as an IP address, and so it prevents using cidr notation in the query e.g., `ClientIP:(172.16.0.0\/12)`

The lambda function should be updated to set the string to an IP.
