Colorer characters printed out on windows

Here is the output of codecov, where there are some unwanted characters like �[90m==>�[0m

D:\foo>codecov

I use:

• Win 10.0.18363 Build 18363 (both cmd and powershell)
• Python 3.7.4
• Codecov py-v2.0.15 - https://codecov.io/

A workaround is to use --no-color switch. However this should be solved, codecov should detect the platform.

[raczben]

I suggest to use colorama or termcolor or any other handy tool for colored output, instead of the current, platform specific way.

Colors work properly in PowerShell command prompt, however it does not work in cmd prompt.
