Reduce distributed package size - move unit test values out of the big npz files
A few of the files in test/
are quite large:
17M DCS_test.npz
15M GDS_test.npz
6.5M 2019-03-27_H1DARM_OLGTF_BB.xml
In discussion with @madeline-wade, she thinks that only a portion the DCS/GDS files are needed. Removing them could greatly reduce the size of the package.
