0.2.0

Added a .cleanUp() method to cancel coroutine Jobs and channels and release recorded emissions to avoid running out of memory if you have a lot of emissions recorded and a lot of tests doing that. Discussed in #2 .

val emissions = flowOf(1,2,3).record()
emissions shouldEmitNext 1
emissions.shouldEmitNext(2,3)
emissions.cleanUp()  // <-- new in 0.2.0
