Update project alumni data

[NihalDR]

This PR updates the project alumni information by adding "Akash B V" information, Hamze Dokoohaki image aspect ratio update and adding image of Rohan Sasne

I have even researched on finding image of tony Gardella Former Project Manager Graduate Student, University of Michigan.
But I could'nt find any it would be great if you can help me in getting the picture of him so that alumni page would be proper.

This is how it looks after update

Thank you for contributing this. Because url-based photos have so frequently broken, I think it would make more sense to put the photos in the repository. That may be beyond the scope of this PR; if so, someone should create a new issue before merging this one.

@dlebauer I can implement storing photos in repository as you said if you assign me to do I'll proceed or shall i open the issue to discuss on this?

[dlebauer]

@NihalDR Yes please, you can store images in the repository. Thanks!

[NihalDR]

@dlebauer sure sir will work on it.
