Add Python code for particle swarm optimization

[Arunkumar0258]

I want to add this new algorithm as part of ML optimization algorithms. It is a new algorithm and also has visualizations for optimizing for global minima. This is a(n):

• [x] New algorithm
• [ ] Update to an existing algorithm
• [ ] Error
• [ ] Proposal to the Repository

Details:

Particle swarm optimization is an algorithm used for function optimization just like Gradient descent in machine learning.
