Remove a bunch of old Python packages

[Adam <adam%netbsd.org@localhost>]

Hello,

Here is a list of some Python packages that I would to to remove. These are old, unmaintained, and probably useless, especially with the latest release of Python. No other packages depend on them.

archivers/py-bz2file - old 2014
devel/py-unit - old
net/py-adns - old 2007
net/py-beanstalkc - old 2014
net/py-socketpool - old 2013
graphics/py-piddle - old 2002
graphics/py-gdmodule - old 2016; Python 2.7 only
security/py-denyhosts - old 2020-05-19, does not build, uses distutils
security/py-mcrypt - old; Python 2.7 only
textproc/csvtomd - dead upstream; 8 years
textproc/py-Excelerator - old 2009
textproc/py-pytoml - old 2019
www/py-python3-digest - old 2012

I am going to remove them within a week, if there is no objection.

Kind regards,
Adam
