Bulk import from info provider

[riacob]

Is your feature request related to a problem? Please describe.
I want to transfer 170+ parts from an excel sheet to parts-db.
Importing it with the normal import functionality, regardless if the spn# is present or not, does not automatically consider the import to be "from info provider", thus requiring manual copy, paste, and stock setting for every single part.

Describe the solution you'd like
An extra import option, be it a separate menu item or a checkmark, to import CSV files containing spn#, stock, and category, and automatically fetching data for each of them from the selected info provider.

Describe alternatives you've considered

Additional context
In my particular situation, i need to move from a google sheet, which has all my parts in it, to parts-db.
And, in the future, be able to seamlessly import order history from LCSC to part-db, as I'm currently manually copying the mpn# into the google sheet, then using IMPORTXML magic to fetch the data, which is very inefficient.

Proposed solution is a for loop calling the import from info provider function with the mpn# as param, then setting category and stock from csv, and fetching the data. Repeating this n times.
