feat: Add And1 class using nested if statements for divisibility check

Add a program that:
- Takes two integer inputs from the user
- Checks divisibility by 3 and 5 using nested if statements instead of logical operators
- Demonstrates an alternative approach to compound condition evaluation
- Outputs whether each number is divisible by both 3 and 5.
