Uniwind support

All my view with uniwind collapsed

Hey, thanks for opening this issue and sorry it took a while! I took a closer look at Uniwind's internals and am, unfortunately, quite sure it'd be technically impossible or at least very hard to add Uniwind support to Boost. Unlike Nativewind for example, Uniwind does not seem to have an interoperability layer to auto-transform className to style on third-party components. They wrap Text and View in their own wrapper components that do this job. When Boost rewrites Text and View to its own native host components (which happens before Uniwind, due to the way Babel and Metro work together), Uniwind can't do that anymore and all className styles collapse.

So, for now, I've documented this as a known incompatibility and the only solution I can offer right now would be to switch to Nativewind, which is compatible with Boost (with some smaller gotchas).

Open to any PRs or creative ideas for Uniwind support, however. I'll keep this issue open.
