openbabel: Upgrade to 3.0.0

Upstream changelog
==================

Open Babel 3.0.0

@ghutchis ghutchis released this on 10 Oct - 29 commits to master since this release

This release represents a major update and is strongly recommended for all users.

It also removes deprecated components and breaks the API in a few places. For \ 
information on migrating from the previous version, please see:
https://open-babel.readthedocs.io/en/latest/UseTheLibrary/migration.html#migrating-to-3-0

We intend to move to semi-annual releases in Spring and Fall, with bug fix \ 
releases as needed.

A sample of major new features:

    Code for handling implicit hydrogens and kekulization has been entirely \ 
replaced. As well as being accurate, the new approach is much faster.
    Speed of reading and writing SMILES has been improved by more than 50-fold.
    Removal of the old 'babel' binary in favor of the newer 'obabel' \ 
command-line tool.
    New improved fragment-based 3D coordinate generation code as part of Google \ 
Summer of code 2018/2019. Significantly faster and more accurate: \

    (Please cite J. Cheminf. (2019) v11, article 49 if you use the new 3D \ 
coordinate generation.)
    New API for handling reactions stored as molecules (e.g. Reaction InChI, etc.)
    New API for copying part of an OBMol as a substructure
    Support for Maestro file format, contributed by Patrick Lorton of Schrodinger

There are an incredible number of improvements, minor features and many bug fixes.

Open Babel 2.4.0 (2016-9-21)

This release represents a major update and should be a stable upgrade, strongly \ 
recommended for all users.

Note that this release deprecates the babel executable in favor of obabel. A \ 
future release will remove babel entirely. For information on the differences, \ 
please see the documentation.
