[@material/react-select] no dense prop

[kino90]

Hello. I'm building a form with all fields (@material/react-text-field) set as "dense" to be smaller. In this form I also have a Select component, but the 'dense' prop is missing, so it's taller than other inputs.

I think all inputs should have it, for consistency. Will that be added to the lib or should I implement a css class just for that?
