4f185329f4 Streamline test skipping based on supported features
This adds a new test decorator: skip_unless_feature(). The argument is
the same as passed to features.check(). If the feature is not supported,
the test will be skipped.

This removes several kinds of boilerplate copied and pasted around tests
so test feature checking is handled and displayed more consistently.

4cd4adddc3 Improve handling of file resources
Follow Python's file object semantics. User code is responsible for
closing resources (usually through a context manager) in a deterministic
way.

To achieve this, remove __del__ functions. These functions used to
closed open file handlers in an attempt to silence Python
ResourceWarnings. However, using __del__ has the following drawbacks:

- __del__ isn't called until the object's reference count reaches 0.
  Therefore, resource handlers remain open or in use longer than
  necessary.

- The __del__ method isn't guaranteed to execute on system exit. See the
  Python documentation:

  https://docs.python.org/3/reference/datamodel.html#object.__del__

  > It is not guaranteed that __del__() methods are called for objects
  > that still exist when the interpreter exits.

- Exceptions that occur inside __del__ are ignored instead of raised.
  This has the potential of hiding bugs. This is also in the Python
  documentation:

  > Warning: Due to the precarious circumstances under which __del__()
  > methods are invoked, exceptions that occur during their execution
  > are ignored, and a warning is printed to sys.stderr instead.

Instead, always close resource handlers when they are no longer in use.
This will close the file handler at a specified point in the user's code
and not wait until the interpreter chooses to. It is always guaranteed
to run. And, if an exception occurs while closing the file handler, the
bug will not be ignored.

Now, when code receives a ResourceWarning, it will highlight an area
that is mishandling resources. It should not simply be silenced, but
fixed by closing resources with a context manager.

All warnings that were emitted during tests have been cleaned up. To
enable warnings, I passed the `-Wa` CLI option to Python. This exposed
some mishandling of resources in ImageFile.__init__() and
SpiderImagePlugin.loadImageSeries(), they too were fixed.

d50445ff30 Introduce isort to automate import ordering and formatting
Similar to the recent adoption of Black. isort is a Python utility to
sort imports alphabetically and automatically separate into sections. By
using isort, contributors can quickly and automatically conform to the
projects style without thinking. Just let the tool do it.

Uses the configuration recommended by the Black to avoid conflicts of
style.

Rewrite TestImageQt.test_deprecated to no rely on import order.

4de5477b61 Remove unnecessary unittest.main() boilerplate from test files
With the introduction and use of pytest, it is simple and easy to
execute specific tests in isolation through documented command line
arguments. Either by specifying the module path or through the `-k
EXPRESSION` argument. There is no longer any need to provide the
boilerplate:

    if __name__ == '__main__':
        unittest.main()

To every test file. It is simply noise.

The pattern remains in test files that aren't named with `test_*` as
those files are not discovered and executed by pytest by default.

7da17ad41e Improve pytest configuration to allow specific tests as CLI args
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.

At present it’s only possible to save the current frame of an MPO, not
the MPO in its entirety. Added testing verifying as much.
