Colorama

* https://github.com/tartley/colorama/pull/139 Add alternative to 'init()',
called 'just_fix_windows_console'. This fixes many longstanding problems
with 'init', such as working incorrectly on modern Windows terminals, and
wonkiness when init gets called multiple times. The intention is that it
just makes all Windows terminals treat ANSI the same way as other terminals
do. Many thanks the njsmith for fixing our messes.
* https://github.com/tartley/colorama/pull/352 Support Windows 10's ANSI/VT
console. This didn't exist when Colorama was created, and avoiding us
causing havok there is long overdue. Thanks to segeviner for the initial
approach, and to njsmith for getting it merged.
* https://github.com/tartley/colorama/pull/338 Internal overhaul of package
metadata declaration, which abolishes our use of the now heavily
discouraged setuptools (and hence setup.py, setup.cfg and MANIFEST.in), in
favor of hatchling (and hence pyproject.toml), generously contributed by
ofek (author of hatchling). This includes dropping support Python3.5 and
3.6, which are EOL, and were already dropped from setuptools, so this
should not affect our users.
* https://github.com/tartley/colorama/pull/353 Attention to detail award to
LqdBcnAtWork for a spelling fix in demo06

* Add support for pickling with the ``dill`` module.

* Re-org of README, to put the most insteresting parts near the top.
* Added Linux makefile targets and Windows powershell scripts to automate
bootstrapping a development environment, and automate the process of
testing wheels before they are uploaded to PyPI.
* Use stdlib unittest.mock where available
* Travis CI now also builds on arm64
* Demo06 demonstrates existing cursor positioning feature
* Fix OSC regex & handling to prevent hang or crash
* Document enterprise support by Tidelift

* Fix release 0.4.2 which was uploaded with missing files.

* 228: Drop support for EOL Python 3.4, and add 3.7 and 3.8. Thanks to
hugovk.
* Several additions and fixes to documentation and metadata.
* Added Tidelift subscription information.

* Fix issue 196: prevent exponential number of calls when calling 'init'
multiple times. Reported by bbayles and fixed by Delgan.
