Ability to specify corner radii

[wbobeirne]

Had another use case I'd like to see added, I have an element with top left and top right radii but not bottom left / right. It'd be cool if for radius, we could pass an object / array for individual radiuses, something like:

modalOverlayOpeningRadius: { topLeft: 8, topRight: 8, bottomLeft: 0, bottomRight: 0 }

Alternatively #1831 and this could be combined into an option that allows you to specify a custom path altogether for the most flexibility, if adding a bunch of new options is annoying.

@wbobeirne there have been requests to set these things separately before. I would certainly be open to a PR if you would like to add this feature!

I'll scope out a PR, thanks for the blessing!

I've added support for this in #2116
