Resolved several issues with the forecast module tests. Library import errors were resolved by prioritizing the conda-forge channel over the default channel. Stalled ci runs were resolved by adding a timeout to the HRRR_ESRL test. Items 3 and 4 of issue #293.
It adds a test requirement, pytest-timeout, that is not particularly popular. The pytest-timeout plugin is part of the pytest-dev organization, though, so it shouldn't become abandonware. For now, I think this is preferable to writing our own timeout code.
Still more work to do to fully resolve #293, but this at least gets the builds working most of the time instead of none of the time. Assuming the Travis/Appveyor builds pass, I'll merge this Monday afternoon/evening unless there are objections.
