Collections deprecated in 3.8

[sabato-chris]

Using the schedule module with my project, and testing with pytest, yields a warning about 3.8 dropping support for collections being called in the way its used.

Running python 3.7.3 with schedule 0.6.0 release.

has this merged version not made it's way back to pypi.org yet? I noticed this same warning from an imported module.
