[Bug] API - api.stocks.fa.models.polygon.get_financials - Headers return "Value" instead of "Date"

[deeleeramone]

To recreate:

api.stocks.fa.models.polygon.get_financials(symbol = "MSFT", statement= 'cash')

There is also more data from the source which can be extracted for Fundamentals. There is a total of six groupings of data.

Balance Sheet Cash Flow Statement Income Statement Comprehensive Income General Key Ratios

It follows the XBRL convention:
