Make mapview HABP-community friendly

[relrod]

The initial (NodeJS) version of mapview first came to life on July 29, 2013 -- a year and some months ago. This Haskell rewrite happened in January of this year.

Though it hasn't been tested in practice yet (due to balloon launch failures), I believe it is at the stage where we should begin looking at what we can do to turn it into a system that other clubs can take advantage of for their own launches. Among other things, this means getting it into a state where we can ship it to Hackage and perhaps a Fedora Copr/Ubuntu PPA.

Here is what I see needing to happen for this to pan out:

• We need a landing site that explains:
  • An overview of the pieces of the system. The readme does this right now but is somewhat technical.
  • Information on installing the system
  • Information on setting up the mapview-psc frontend
  • Screenshots of mapview-psc
• Misc. code cleanup
  • Perhaps split some pieces into separate modules.
  • Making use of lens-aeson
  • Making it easy for clubs to edit the parser (even though it requires a recompile)
  • Un-hardcode anything specific to our launches, if possible. Some stuff (e.g. parser) won't be possible.
• Really clear install instructions
  • This is crucial, I think. We have a ton of dependencies. I don't see us giving up many of them, but at minimum we need to at least explain in detail how to install them all and set things up.
  • Explain how to deploy mapview-psc
  • Firewall gotchas between mapview-psc clients and mapview-send
• Make sure mapview-psc works well on mobile.
• Maybe develop a mobile app in addition, but this is way down the road.
  • It could do like the Google Sky Map and Satellite AR apps do and let you hold up your phone and have it show you, based on coordinates and look-angle, exactly where you should be looking. I suspect @kg4sgp would like that.

I've been working on documentation a bit toward this. See https://mapview.noexc.org/ and https://mapview.noexc.org/Configuration.html.
