Unzip hdf5 files into one directory instead of many

[weiji14]

The downloaded zip file stores each HDF5 file in separate subfolders. This Pull Request fixes #33 by modifying the unzipping code so that the files are all in a single folder (the download folder set by the user). I.e. instead of having this:

• download_folder
  • 123456789
    • processed_ATL06_2019*.h5
  • 234567891
    • processed_ATL06_2019*.h5
  • 345678912
    • processed_ATL06_2019*.h5
  • 456789123
    • processed_ATL06_2019*.h5

The unzip will now do this:

• download_folder
  • processed_ATL06_2019*.h5
  • processed_ATL06_2019*.h5
  • processed_ATL06_2019*.h5
  • processed_ATL06_2019*.h5

There seems to be an extract argument (which takes a boolean True/False) that is commented out in the code, should I enable it?

@weiji14 The extract keyword is commented out because it was not yet fully implemented. It would be great to have that functionality for those who do not want to automatically unzip their downloaded files (especially for very large datasets). I think it would be best to keep/set the default behavior as extract=True though.

[weiji14]

Yes, especially since there are ways to read the data inside the zipfile without explicitly unzipping them. Leave that for a separate Pull Request.
