print_error function is not Python3 compatible

Within rql/__init__.py we use the function print_error imported from yapps.

I was trying to test Rich integration with from rql import parse; r1 = parse("Any foo1+1").

As we can see in the picture below, (and here) this function is not yet Python3 compatible (at least for the use of print).

What do we do?

Add a Yapps repository in the Cubicweb group including a patch to support python 3
