Remove setuptools_scm in favor of explicit version management (#156)

setuptools_scm has a few drawbacks to version management by hand, such
as inflexibility for releasing off-tag, and missing info on shallow
checkouts.

As such, revert back to a static version number, with tagged commits as
version bumps.
