Remove broken reporting functionality

This file computes reports for data packages. Part of those stats
depend on accessing the data files that are part of the package. Since
the API for looking up files based on their identifiers has changed,
this portion of the code is currently broken.

I'm commenting it out rather than fixing it, because (a) we don't need
this functionality right now, and (b) the fix would take longer than I
have available for running a needed report. The next time such a
report is needed, we will need to reinstate the portion that looks up
data files.
Move curation tasks for basic package information

The basic package information has been moved out of the
DataPackageStats class and into a new, simplified DataPackageInfo class.
Adding curation task DataPackageInfo
Minor cleanup
Add DOI normalization
Add dependencies to DataONE client libraries
Initial version of resource maps

Updatede settings for using DataONE client library. Added
functionality to generate ORE resource maps for data packages.
Change "rem" indicator to "d1rem"

Since the content of the resource maps is a bit DataONE specific,
change the name, leaving generic "rem" for future use.
