Fix compatibility with tabulate 0.10.0 (#107)

* Fix compatibility with tabulate 0.10.0

Because `tabulate.PRESERVE_WHITESPACE` was replaced with a keyword
argument but was not removed from the module namespace (even though
modifying it no longer has any effect), the only way to check whether we
should pass the new `preserve_whitespace` argument is to examine
`tabulate.__version__`. This required adding a dependency on `packaging`
to parse and compare the version string.

* Changelog entry for tabulate 0.10 support

* Add Benjamin Beasley as a contributor in AUTHORS

* Require tabulate>=0.10.0 to avoid a packaging dependency
