Replace Use of PyZ3950

[thejuliekramer]

Feature

As a part of a plan to upgrade CKAN extensions in use, and in order to improve the way that we manage forks we need to update the use of PyZ3950.

We need to replace the use of outdated PyZ3950 wherever it occurs with the pipy version

Anticipated/hypothesized benefits

• We are going to solve compatibility issues. We are using old repos
• We are going to use a community supported version

Tasks

• #127 Replace github install with pip install from https://pypi.org/project/PyZ3950/
