feat: add magic square algorithms

[namanhegde018-ux]

Description of Change

Adds algorithms for constructing normal magic squares for odd, singly-even, and doubly-even orders.

The implementation uses:

• TURAGAGATI for odd orders
• SAMPUTAVIDHI for doubly-even orders
• VISHAMAGARBHA SUTRA for singly-even orders

Includes self-tests for the generated magic squares.
