Script to generate data4mask.py and data4info.py

[hornc]

On follow-up of issue #84

This was meant to be a question about whether this feature would be useful, but I wanted to check that it was possible to generate the existing data from the isbn-international.org range file XML first. In the process of checking, I'd basically finished writing the script, so here it is as a draft proposal.

If anything needs renaming, or moving, let me know.

I have never seen the closed-source isbntools-dev, and do not know how the current isbnlib dev pipeline works, so I'm not sure how well this will integrate in to your current process. I thought it'd be nice to have a open source mask refresh code which can be generated on demand from the official isbn-international source.

I expect this may need some work to be properly integrated, and I admit I'm not sure who will run this script and when, or even if this belongs in a separate public repo since there are no other stand-alone scripts in this repo.

Changes proposed in this pull request:

• Open source script to create data4mask.py and data4info.py from a request to isbn-international.org ISBN range file XML

• Minor content changes to data4mask.py and data4info.py , but the functionality should be identical.

• RDDATE is taken from MessageDate in the source export_rangemessage.xml (I don't know if it was before)

isbnlib is a very useful tool, thank you for creating it! I hope this is helpful. Happy to discuss.

HI. Thanks for your script.

This is a simpler version of isbntools-dev, some tests and hedge cases are missing but most of the times it should work. However, after many pros and cons I decided (long ago) to not integrate the tool in isbnlib.

Anyway, I suggest that you publish it as a script addon that could be useful for some power users! The present plugin framework used by isbnlib doesn't allow this kind of integration.
