SZP021: Save current search results to corresponding database

[vendral]

1. Create new public function in Database.py which takes files and path arguments and creates new database path.szp
2. Once database is created, save all entries in files to Photo table (make sure it is created first)
3. Call the function in (for testing purposes only, use Filter handler. It will move to Save handler once save button is created): https://github.com/vendral/szperacz/blob/main/szperacz/run.py#L63, provide files and test path path (choose whatever name for a moment)
4. In the long run, save handler will deliver path from user (issue link to be done by @vendral)

Expected DataBase workflow:

• Create database (xxx.szp)
• Connect to database
• Create Photos table
• Update foreach file in files / commit changes
• Close connection
