Overview:
+ LICENSE file now have the lincese for all the data used in GlassPy.
+ Now we have a documentation. Check it out at https://glasspy.readthedocs.io/
+ `glasspy.chemistry` has new `CompositionType`, tools to work with composition arrays, and a featurizer.
+ `glasspy.data` now has the `SciGlass` class to load data from SciGlass.
+ GlassPy now uses the original SciGlass data without any modifications. All the processing is done within GlassPy.
+ `glasspy.nucleation`, `glasspy.thermodynamics`, and `glasspy.relaxation` were removed for now. Please use version 0.3 if you want these functionalities. These subpackages will probably come back in the future, but right now I'm focusing on the data and prediction of glass properties.
+ `glasspy.predict` now has GlassNet and ViscNet as available models. GlassPy is now the oficial home of ViscNet. The ViscNet repository will soon be archived.
+ new `support` submodule with support functions.
+ `glasspy.viscosity` was changed and some functionality was removed. It will be back in the future.
