Enhanced table printing and the removal of text mode

[k4yt3x]

I've been playing around with Rich today, and I'm liking the way it prints tables. Since wg-meshconf is now available on PyPI, and pip installs all dependencies automatically anyways, I'm planning on making a few changes:

• Replace PrettyTable with Rich for the even-prettier output
• Remove the text output format since it is not easy to read whatsoever -- you might as well open the CSV in Excel

I'd like to hear what the community thinks about the changes proposed above. I'm also interested in seeing which of the following styles is more beloved:

Possible style 1: HEAVY_HEAD (with horizontal lines)

Possible style 2: HEAVY_HEAD (without horizontal lines)

Possible style 3: ASCII

You get the idea. See a list of all possible styles here: https://rich.readthedocs.io/en/latest/appendix/box.html#appendix-box
