Some instance-data values may be binary on some platforms, such as userdata and vendordata. Attempt to decompress and decode UTF-8 any binary values. Any binary values in the instance metadata will be base64-encoded and prefixed with "ci-b64:" in the output. userdata and, where applicable, vendordata may be provided to the machine gzip-compressed (and therefore as binary data). query will attempt to decompress these to a string before emitting the JSON output; if this fails, they are treated as binary.
