create a digikey mylists bom and add parts via api

Steps

1. Register an application, subscribe to the MyLists API product, and complete the OAuth 2.0 3-legged (authorization code) flow; MyLists operates on a signed-in user's personal lists so it requires 3-legged OAuth.
2. Call POST https://api.digikey.com/mylists/v1/lists with Authorization: Bearer <token>, X-DIGIKEY-Client-Id headers, and a JSON body naming the new list; optionally call the IsValidListName/ValidListName endpoints first to avoid a name collision.
3. Call GET https://api.digikey.com/mylists/v1/lists to enumerate existing lists and get the new list's listId.
4. Call POST https://api.digikey.com/mylists/v1/lists/{listId}/parts with a JSON body of part entries (DigiKey or manufacturer part numbers and quantities) to add them.
5. Call GET https://api.digikey.com/mylists/v1/lists/{listId}/parts (optionally with a start index/numberOfParts) to page through the list's parts, or GET .../parts/{uniqueId} for one line item.
6. Use PUT .../lists/{listId}/parts/{uniqueId} to update a line, or DELETE .../parts/{uniqueId} / DELETE /lists/{listId} to remove a part or the whole list.
