snapshotDirectory param in assertSnapshot

[andrewjmeier]

I see in the documentation of verifySnapshot it says "For example, if you want the snapshot directory to be determined by an environment variable, you can create your own assert helper like so:"

Why isn't snapshotDirectory exposed as a parameter in assertSnapshot? It's easy enough for me to add

guard let message = failure else { return }
XCTFail(message, file: file, line: line)

And write this myself, but it feels like something I shouldn't have to do.
