Centralised classes/theme

[Zhincore]

Hello!

I've noticed flowbite-react and flowbite-svelte (and I expect the rest of integrations too) implement their own class lists, even thought they are the same across frameworks.

flowbite-react already uses theme.ts that stores all the classes, why isn't this file in this central repository? You have to install it alongside flowbite-* anyway. Then it would be easier to make the style consistent and it would make whole Flowbite more DRY and probably easier to maintain.

Is there any reason it is not like that already?
