* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-031-3/+0
| | | | | | | | | | | | | | | | All of the removed `from __future__ import` were needed in older versions of Python (mostly 2.5.x and below) but later became mandatory in most versions of Python 3 hence are not necessary anymore. More specifically, according to __future__.py[1]: - unicode_literals is part of Python since versions 2.6.0 and 3.0.0; - print_function is part of Python since versions 2.6.0 and 3.0.0; - absolute_import is part of Python since versions 2.5.0 and 3.0.0; - division is part of Python since versions 2.2.0 and 3.0.0; Get rid of those unnecessary imports to slightly clean up the codebase.

| | | | | | | | the decisions are calculated in the C++ code and some issues with the QAM16 constellation in particular. This addresses issue #737. The patch attached to that issue is not actually valid and is only an ordering problem/confusion. I will be adding an example GRC flowgraph that compares the output of the hard decision and soft decision versions to the original input stream to show how they match. Increased testing coverage in the QA to test certain known points as well as random samples.
