add a timer in the problem solving module

[darshangoswami]

I'd like to start by saying thank you! I love this application that you and the community has created. It totally eliminates the hassle of setting up and dealing with Anki and more.

• My suggestion is to add a timer/ stopwatch on the top bar while solving a problem, just like it exists in Leetcode.
• It can really help the user judge their performance on a certain problem so that they can choose the right option for the next repitition.

I'd also be willing to take up this issue and solve it on my own if you think it's a good idea.

Thank you!

@darshangoswami Hi there,

This is an amazing idea, thank you for creating an issue for it & for helping make Repcode better for everyone.
I've gone ahead and assigned it to you, if you have any trouble setting up the dev environment or have any question at all about anything, let me know!
