Refactor variable names and improve code readability in apg.go
Updated several variable names such as 'c' to 'config' and 'al' to 'algorithm' in order to improve code readability and understanding. An additional 'SpellPassword' option was added to provide users the ability to hear their passwords spelled out, enhancing functionality. This improves readability and user experience.
