Error is raised when no variables are specified at the CLI for a netCDF that has groups #143

To reproduce:

  1. To avoid affecting the original test data file, copy the OCO3 test data file (I chose this file because it has groups) from tests/data/OCO3/OCO3_L2_LITE_SIF.EarlyR/oco3_LtSIF_200226_B10206r_200709053505s.nc4 to a new directory, let's say ~/test_temp/oco3_LtSIF_200226_B10206r_200709053505s.nc4.

  2. Then run the subsetter — without any variables specified — at the command line:

    poetry run l2ss-py ~/test_temp/oco3_LtSIF_200226_B10206r_200709053505s.nc4 ~/test_temp/oco3_LtSIF_200226_B10206r_200709053505s_subsetted.nc4 --bbox -180 -90 180 90

The following error is raised:
