feat: Add Inputs class to demonstrate reading different data types from user

Add a program that:
- Takes roll number (int), name (String), and marks (float) as input
- Uses `Scanner` to read and store user input
- Prints the collected data to the console
- Demonstrates handling of multiple primitive data types via standard input.
