Hi Team,
I am using OpenTUI for one of my projects and while writing padding and margin values for components (solid js), I felt I have been writing left and right a lot.

Since I have used tailwind for my projects, I felt like X and Y attributes for both margin and padding should be a simple addition to make writing these values a little easier instead of left right and top and down separately if the values used are same.

I have already linked the PR to this issue if you guys find it acceptable to merge it.

Would be more than happy to discuss more on this.

Thanks for building a great library to use, it's really cool 😄
