Decouple plotting routines from `SkyScanResult`

[mlincett]

The plotting methods of SkyScanResult are fairly complicated and could benefit from some refactoring.

I think it would be sensible to decouple all the plotting stuff from SkyScanResult and collect those in a separate SkyScanPlotter class.

Let me know if you have anything against it @ric-evans and @tianluyuan

I plan to move forward with this in #21

[tianluyuan]

Sounds good. I support this 👍

[ric-evans]

Good idea, we could also use some unit tests to make sure we don't delete something in the refactor

FWIW I run pylint locally which produces an error when files get beyond 1000 lines. some of pylint's errors are more like suggestions than steadfast rules, but I've found a majority of them helpful

I wrote a gist for this exact purpose https://gist.github.com/ric-evans/aa55b6d054ef1fae9464b992631aa90d It does require multiple commits to main, but that's unavoidable

Note: You'll have to manually stop the CI to avoid an auto-release

@ric-evans would you mind doing this for me to duplicate results.py?

Sure thing -- I'll leave the actual trimming to you. I'll put it on my list for tomorrow

@mlincett done. Check out https://github.com/icecube/skyreader/blob/main/skyreader/plot/plot.py, it has duplicate line history (blame) as result.py. You'll now need to remove what you don't want to keep from each file and fix the imports

[mlincett]

Fixed in #28
