[AGIPD][FF] Styling modification for both FF notebooks:1st nb cell, and removing uneeded imports
1 unresolved thread
This is a small MR for removing/modifying 1st nb cell in the main FF notebook and the summary notebook.
The main drive behind this MR is to correct h5path_ctrl
as this has already been changed in the summary notebook to ctrl_source_template
with a value fit for Extra-data.
There has been as well a cleanup of the unneeded imports.
