Drop Python 2 support; enhance CSV with markdown performance

• Dropping Python2 support, existing Python 2 users should be fine with pip>=9.0. See https://python3statement.org/practicalities/.

• add pipe_tables, raw_markdown options. See README for details. This for example will speed up CSV with markdown cells a lot (trading correctness for speed though.)
