How to update csv in resources folder?

[royopa]

Hi @alvarobartt !

I saw that the index symbol "XAUFIX=" is available on investing website (see https://www.investing.com/indices/lbma-gold-fixing-price), but this index is not linked on resources/indices.csv.

Could you explain how to update the csv files inside resources folder? Or maybe how to get the news ids from investing page.
If you have any webscraper script maybe could be useful have the script running from time to time to keep up the list up to date. What do you think?

Best regards and thank you so much about the awesome work in this library!
