feat: add FluxRecord.getRow() with response data stored in List

[michaelahojna]

Proposed Changes

Adding possibility of accessing response data in List FluxRecord.getRow().

In case of using pivot on data, where field contains labels that occur by default in the annotated CSV (f.e. "result" or "table"), could be duplicated column names in response. In that case FluxRecord.getValues() (Map), which can hold only unique keys, doesn't show complete data. This edge case is solved by using FluxRecord.getRow() (List).
