access package version in tools/gitcount

[jGaboardi]

xref pysal/spaghetti#654, pysal/libpysal#434

In order to take advantage of using tools/gitcount.ipynb with the newly adopted versioneerschema, the version import cell must be split into two cells and changed from:

# get __version__
f = "../{package}/__init__.py".format(package=package_name)
with open(f, "r") as initfile:
     exec(initfile.readline())

to:

# get __version__
%run ../spopt/_version.py

__version__ = get_versions()["version"]

The diff looks fine (I haven't run the notebook).
