Support for an option to specify the number of problems solved for each level of difficulty

[sgc109]

First, thank you for developing and sharing this gorgeous project!

I would like to propose an additional feature for nicer user experience.

At this moment, the badge is just showing the total number of problems solved.

But, how about showing each number of problems solved for level of difficulty like Leetcode official profile?

I can easily add an option to display the number of problems solved on a given level of difficulty. Showing all three levels would then require three different badges.

I could also combine the numbers into a single badge but it would be a long unstyled string. Quick example:

The main limitation here is that this project is just an helper on top of https://shields.io/ badges, which are pretty minimalistic in nature.

Happy to hear your suggestions.

By the way, thank you for opening this issue. It's the first request I get on my repositories.

I'm glad to know someone finds this project useful.
