Replace flow types with TypeScript?

[benmccann]

I wonder if there might be any interest in replacing the flow types with TypeScript? It would be more familiar to most users and remove the need for the @types/aria-query package. It looks like it wouldn't be a difficult migration

Yes please. I’d prefer tsdoc comments that pull types from hand-written dts files.

If there’s a way to generate flow files from those, so it’s not a breaking change for Facebook, that’d be ideal.
