9980981c2e De-zigzag JPEG's DQT when loading; deprecate convert_dict_qtables 
Re-order the JPEG quantization tables to normal order when
loading. This wastes a few CPU cycles if you don't need them.
But it has the advantage of hiding the zigzag order JPEG
implementation detail of these tables completely from Pillow
users.

This difference has led to cases where:
* arrays in zigzag order were taken from a dict and passed
  directly as a qtables parameter, causing them to be "zigzagged"
  again by libjpeg.
* dicts with lists in normal order being passed to
  JpegImagePlugin.convert_dict_qtables, causing them to be
  unnecessarily "de-zigzagged".

6db0843af4 Add support for 16-bit precision JPEG quantization values 
Don't force JPEG quantization to be baseline-compatible

Quantization values will not be limited to values 1..255 and may
be 16 bits if needed. This may cause compatibility issues.

64032061c0 Move several imports to the top-level of the file 
This better follows PEP 8 style guide:

https://www.python.org/dev/peps/pep-0008/#imports

> Imports are always put at the top of the file, just after any module
> comments and docstrings, and before module globals and constants.

This also avoids duplicate import code within the same file.

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.
