-------------------
* Updated provenance utils, added checks in for missing data in input RO-Crate,
and allowing to continue but logging errors in the process
* Add ``HierarchyToHiDeFConverter``, a class to convert a hierarchy network
(in CX2 format) to a HiDeF format nodes and edges lists.
* Add ``NDExHierarchyUploader``, a class for uploading hierarchy and
its parent network to NDEx.
* Updated ``cellmaps_utilscmd.py`` ``apmsconverter``, ``ifconverter``,
``crisprconverter`` to support tissue as well as output
``data_info.json`` file to resulting RO-Crate so subsequent tools can
more easily get provenance information

files and updated readme.txt file
