Skymap integration
Merge request for the integration of an official skymap plotter for shifter tools and the collaboration. The goal is to have km3astro coord transformation and plot skymap as a base for new user and development.
I added function to km3astro.plot for plotting skymap.
There is 3 main methods: - skymap_hpx which take a fits file and plot it (for GW alert) - skymap_list which take a list of alerts and plot them on the visibility map of a given detector - skymap_alert which take an alert and plot it on a given frame with the horizon view lane and the galactic plan
in examples, you will find test_plot.py which show how to produce skymap with this function.
For now all pipelines work except "doc". I did not succeed in solving this issue so help is welcome.
Cheers.
