説明
Describe the bug I have a bigquery schema that uses nested repeated records, any reference of a field in the nested record throws an error like this:
Error: Error: Cannot access field balance on a value with type ARRAY<STRUCT<price FLOAT64, balance FLOAT64, currency_iso STRING, ...>> at [5:41]
I think for this to be solved cube.js needs to use the UNNEST sql keyword to flatten the array of records:

The issue was mentioned at the end here, but it was closed so I opened a new one: #182
