New reconstruction chain in the webApp

[mchiusi]

In this PR, I have added the possibility to run the new reconstruction chain from the 3D display app, allowing users to view its outputs on the screen. Users now have the option to display cluster seeds from the new reconstruction chain, which includes the new coarse seeding and the new seeding algorithm, or from the default chain by simply interacting with a switch.

The scripts required to run the new reconstruction chain were already present in the Python framework. When calling for new events from the app, both chains are executed, so that the final user can compare the two chains applied to the same event. The new_radii_chain function has been updated accordingly. The dataframes are then processed and stored in the usual hdf5 files, where a new key has been added. This key allows for distinguishing between the new chain and the default chain and can assume the values of 'new' or 'default'.

Here's an example of a photon (200 pileup) processed by both chains. The difference in performance is truly impressive.

Great! General comments:

• the key "new" for the new chain is not ideal, because as soon as we add a third chain (or a small variation of one of the current two chains) it will have to be changed
• following the same reasoning, it is likely better to use a widget with more than two options

I've added a dropdown menu instead of a switch so that we can easily add multiple chains in the code. Now the new chain is called coarse seeding chain.

Additional minor comments:

• Could you please replace "t" by "T" when showing the transverse momentum?
• Same for "Threshold in [mipₜ]", where you can also remove the "[" and "]"
• Why are eta and phi within parenthesis and not pT? Can you uniformise?
• I think you could add the "Select a particular clustering radius: " slider to the right of "Select manually an event:", so to gain vertical space.
• Replace "Pages" by "View", or similar, since it is IMO clear

Once this is addressed I am ready to approve. What about @isehle?

Implementations done! Now the page layout is a bit better!

All set. Thank you for all the work, and for addressing the (many) comments.
