Be able to load zipped version of event/geometry files in a generic way

[sponce]

- 'moved' and adapted from phoenix-helpers repo where it was created initially by mistake -

The gain in size is typically around a factor 10, so for a web based application, it would make sense to be able to use zipped versions of our data files, both for events and geometry. Now I had a look at the code, and the thressjs GLTFLoader does not seem to support it natively, so we would have to write it ourselves

answer from @9inpachi

We already do this but only in the event data import, not through the URL or anywhere else. The same logic could be extracted and reused though.

summary of discussion

This is for now Atlas specific and event specific. It should be available to all and also for geometry ideally

Steps remaining :

• allow zip files for default event files
• allow zipped geometries

I've now added zip loading to LHCb events. It should probably be there by default for all cases though.
Remains 2 main point : allow zip for default event file and allow zip for geometry

Is this done?

The zipped geometry is done indeed. I'm not sure what I meant for "default event file", but it's probably not done.
