The `py36` flag now uses a tuple comparison to correctly handle future
major version. The unit test file also now uses `py36` as exported by
the _util module, rather than re-testing `sys.version_info`.
Now, for functions which accept either a path or file object, the
predicate will pass on Paths and not attempt to call .read on them
before opening.
The pathlib module was added in 3.4 but os.path functions did not start
accepting path-like objects until 3.6, so that is the version after
which this implementation is defined.
Added a unit test to make sure isPath accepts Path objects. The unit
test is skipped if python version is not 3.6 or later.
When bytes warnings are enabled with the '-b' argument, the PdfDict
class would emit a warning.

Object attributes are always type str, so can safely encode them without
a type check. Observe:
$ python3
>>> o = object()
>>> setattr(o, b'foo', b'bar')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: attribute name must be string, not 'bytes'
The previous test configuration made it difficult to run a single test
with the pytest CLI. There were two major issues:
- The Tests directory was not a package. It now includes a __init__.py
file and imports from other tests modules are done with relative
imports.
- setup.cfg always specified the Tests directory. So even if a specific
test were specified as a CLI arg, this configuration would also always
include all tests. This configuration has been removed to allow
specifying a single test on the command line.
Contributors can now run specific tests with a single command such as:
$ tox -e py37 -- Tests/test_file_pdf.py::TestFilePdf.test_rgb
This makes it easy and faster to iterate on a single test failure and is
very familiar to those that have previously used tox and pytest.
When running tox or pytest with no arguments, they still discover and
runs all tests in the Tests directory.
