Enlighten

New Features:
- Escape sequences automatically detected when determining bar width
When [offset](https://python-enlighten.readthedocs.io/en/stable/api.html#counter-offset) is set, this functionality is disabled

Changes:
- Flush streams on program exit
Prevents escape processing from being disabled on Windows before all data with written to the terminal
- Use [Blessed](https://pypi.org/project/blessed) for Windows support
Windows support in Enlighten has been [merged](https://github.com/jquast/blessed/pull/110) into [Blessed](https://pypi.org/project/blessed)


Housekeeping:
- Update FAQ
- Cleanup Examples
- Unicode cleanup (Python 2.7)
- Add tests and metadata for Python 3.8 Final

- Catch additional exception for invalid filehandle when checking terminal size in WIndows

- Provide fallback for Windows terminal size (80x25)

- Bugfix: Account for stream without `encoding` attribute
- Add PEP 508 dependency logic
- Manager logic when using `Counter` directly now uses `get_manager()`

- Windows is now supported!
- Bugfix: Don't assume stdout is always UTF-8

- Support for [colorized progress bars](https://python-enlighten.readthedocs.io/en/stable/examples.html#color)
- Support for [multicolor progress bars](https://python-enlighten.readthedocs.io/en/stable/examples.html#multicolored)
- Counters return a generator that [automatically updates](https://python-enlighten.readthedocs.io/en/stable/patterns.html#automatic-updating) the count as it yields elements from one or more iterables
- Add offset argument to [Counter](https://python-enlighten.readthedocs.io/en/stable/api.html#enlighten.Counter)
- Allows accounting for non-printable characters in ``bar_format`` and ``counter_format``
