New generator for the CCID readers pages

Since Python 2.x is no more maintained from 1st January 2020 I had to move the script to generate some CCID pages to Python 3.

These pages are the famous ones available from https://ccid.apdu.fr/#readers:

• Supported readers
• Should work readers
• Unsupported readers
• Disabled readers

Technology update

The previous Python script used templayer. templayer is no more maintained since 2009 and only works with Python 2.
I now use Jinja2.

It can be about the information provided on the pages or the graphical design of the pages (you may have noted that I am not a website designer).
