py-mako: updated to 1.0.12

1.0.12
[bug] [py3k]
Fixed regression where import refactors in Mako 1.0.11 caused broken imports on \ 
Python 3.8.

1.0.11
[change]
Updated for additional project metadata in setup.py. Additionally, the code has \ 
been reformatted using Black and zimports.

1.0.10
[bug] [py3k]
Added a default encoding of “utf-8” when the RichTraceback object retrieves \ 
Python source lines from a Python traceback; as these are bytes in Python 3 they \ 
need to be decoded so that they can be formatted in the template.
