Export SplitAtomAction type

[adamscybot]

A minor request.

The SplitAtomAction type is not exported from the package, and is useful in several contexts. In my case, I am wrapping splitAtom, and would like to expand on the base type, but it could just as well be needed in some patterns where you pass around the "action" object in application code.

I would usually try to extract it somehow but here it is impractical due to TS limitations on extracting return types of overloaded functions.

That's fair. Okay, let's export it. Only in splitAtom.ts, not in other index files. I hope it works for you.
