Issue Description

Our project is moving to Swift Package Manager from Carthage (OHHTTPStubs 8.0.0) and found out that Mocktails are not supported by the package generated by the project, any chance this gets supported soon?

Previous implementation:

OHHTTPStubs.stubRequests(usingMocktailNamed: file, in: self.bundle, error: &error)

I'd like to use Mocktails, too. Via SPM.

It looks like @fabrizioCorut has an open PR for this - #340.
