from_file() meta_data column selection

[Anis-Bouhamadouche]

Within the function from_file(), the meta parameter allows you to extend your taxonomy with additional attributes. You can add multiple columns to your Excel file and those will be grouped into a dictionary object for each row, in a column called meta_data. Every column that is not within ["id", "name", "level", "grouping", "parent", "score", "weight", "children"] will be considered.

This issue aims to extend from_file to allow you to select which columns that are not part of ["id", "name", "level", "grouping", "parent", "score", "weight", "children"] to be considered as the current implementation takes all of those columns.
