[feat] add context columns from input dataset into recipe Asset values downloader #56
Description
When extracting data, it is sometimes necessary to retain contextual information, not just time-based data.
With the asset value downloader recipe, it is currently not possible to transfer contextual data from the input dataset to the output.
As a result, when extracting multiple data points with different start and end dates, it can become challenging to reconcile contextual information.
I would like to have the ability to select specific columns from the input dataset to be directly copied into the output dataset.
This issue is related to #54.
