📝 Description of the feature

Implement a new function that enables importing a CSV file containing parts to be added to the AVL (Approved Vendor List). This function should replicate the manual process in Sherlock, where users navigate to 'Libraries', select 'Approved Vendor List', and then click 'Import Parts'.
