This MR addresses the integration for a new JF strixel at SCS
The main purpose of this MR is to integrate the new detector. Additionally, to update the strixel_configuration to be able to update the jfstrixel functions to switch between the different jf strixels we have now at HED(A0123) and SCS(A1256)
As I did previously with epix100 and GH2, I saw this opportunity to collect the Jungfrau modules in a dedicated directory. I have also included the 2 new .npz files which @hammerd produced at calng!76 (merged). This enables us to avoid creating the LUT for every train. This led to removing some functions from jfstrixel.
I updated the dark notebook as well as the test_jungfraulib file to adapt the library path update.
