This cleans up strax' test helpers file, which contains mainly hypothesis strategies for making random records and peaks for testing data processing routines.
There are now no side effects from importing it -- in particular, we no longer mock numba for performance during tests. This makes the tests take slightly longer, but only if the compilation cache is not present (e.g. on Travis or after changes). Since we use numba in production we should clearly also test with it. Also, since numba is considering using strax as an integration test (numba/numba-integration-testing#29) I'm sure they would appreciate if we don't replace
sys.modules['numba']
with a MagicMock...The test helpers file is made accessible as strax.testutils, since some of the functions defined in it could be useful in writing tests for straxen.
