Implemented command-line interface for test executable

[KaranSinghDev]

Introducing command-line interface to the src/test executable to allow selecting specific tests or algorithms to run.

Previously, ./test executed all available tests. Now, users can specify a command:

• Running ./test with no arguments maintains the original behavior (runs all tests).
• Running ./test <command> [arguments] executes only the specified test/algorithm.

Objective:

• To give flexibility for running targeted tests or algorithm simulations.
• Making experimentation easier without needing code modifications.

Usage Examples:

Run only Shor's algorithm for N= 15

./test shor 15

Expected Otucome :
Testing Shor: Factorizing N = 15...
Quantum period find found the period of 11^x mod 15 to be 2
Shor found a factor of 15 to be 5
Shor algorithm found a factor of 15 to be 5
Finished Shor factorization test.

Run only Grover's search for omega=6 on 3 qubits

. /test grover 6 3

Expected Outcome:
Testing Grover: Searching for state 6 using 3 qubits...
|000>: amp-> -0.0883883 + 0i, prob-> 0.0078125
|001>: amp-> -0.0883883 + 0i, prob-> 0.0078125
|010>: amp-> -0.0883883 + 0i, prob-> 0.0078125
|011>: amp-> -0.0883883 + 0i, prob-> 0.0078125
|100>: amp-> -0.0883883 + 0i, prob-> 0.0078125
|101>: amp-> -0.0883883 + 0i, prob-> 0.0078125
|110>: amp-> 0.972272 + 0i, prob-> 0.945312
|111>: amp-> -0.0883883 + 0i, prob-> 0.0078125
Grover result: want 6, got 6
Finished Grover test.

Run only the QFT tests

./test qft
