Update code to run under Python3 + Conda packaging

• Updated to work with Python 3
• Added a unit test to ensure basic functionality of coverplot.get_command_args()
• Updated list of platform specific dependencies to be installed when installing coverplot in dev mode (see setup.py)
• Installed and tested coverplot against Python3.[6,7,8] using tox
• Formatted Python code to conform to the PEP8 style guide
• Created conda packages for coverplot that can run on Python3.[6,7,8]
• Updated .gitlab-ci.yml to run a linter and unit tests for Python3.[6,7,8] in GitLab CI pipeline

Is rdseed available on GitLab? And if so, is there a way to change GitLab configuration/profile (not sure those are the right terms here) to set an environment variable and path for rdseed? That would allow the jobs python3.6, python3.7 and python3.8 under Pipeline #755 to pass. All the unit tests successfully run on my computer but I have rdseed installed.

rdseed is owned and maintained by the DMC. How much effort would it take to use obspy instead of rdseed and msi? Otherwise we'll need to make conda package for them

Not sure yet how much time it would take to update the code to use obspy instead of rdseed. I will take a closer look at it at some point this week.

No worries. For now, in the interest of time, lets add rdseed and msi to the packaging list for PASSOFT. We'll want msi on there anyway as our users often need that tool.

lets also add dataselect, and query the data group for any others

rdseed is https://github.com/iris-edu-legacy/rdseed

Sounds good. I will work on it once I am done packaging all the other listed utilities.
