V2 interactive plotting

[krisvanneste]

This PR contains some modifications to make interactive plotting in a notebook work.

The main change is the transfer of code writing information to the run_info attribute of the sourcespec output object, from the write_output function in ssp_output.py to a dedicated _update_run_info function. This function is then called at the end of the ssp_run function in source_spec.py rather than in write_output.

I also considered writing the end_of_run and end_of_run_tz info to run_info instead of config, but this would require additional changes in ssp_plot_spectra.py, ssp_plot_stacked_spectra.py, ssp_plot_stations.py and ssp_html_report.py, where this information is used in functions creating subelements of the plot/output. Instead of relying on the global config object, the run_info object should be passed to these functions. I'm not sure if you would want to do that.

With these changes, it is possible to plot figures interactively in a notebook, by setting:

config.plot_show = True
config.plot_save = False

This works for traces, spectra, stacked spectra and the boxplot.
I had to make some modifications in ssp_plot_stations to make it work for the station plots as well. This is partly due to the older versions of pyproj and matplotlib that I use. With these changes, plot_stations works without errors, but there may still be a problem: I obtain 4 plots, 1 with stations colored by magnitude, and 3 identical plots without stations. According to the code I would expect 2 plots, the second one with stations colored by fc. Could you test this too?
Another idea could be to add an option to plot_stations to choose between coloring by magnitude, fc or both?

Let me know what you think.

Hi Kris,
thanks for this PR!

I checked it on the notebook you sent me a while ago, and I can confirm you that it works, with the only problem on the station map.

I can look into this problem in the next days.

Hi Kris,
unfortunately, I didn't have time to look into this today.

I'm taking one week off and will back to business on Nov 3.

No problem Claudio, have a nice week off!
