[LPD] New notebook for injecting constants from stored h5files

This MR is related to https://git.xfel.eu/gitlab/detectors/cal_db_interactive/merge_requests/70

Description

This MR introduces a notebook to inject calibration constants from h5files.

It is planned to be used for LPD to inject 4 gain constants to the database.

Constant names:
1- FFMap
2- BadPixelsFF
3- RelativeGain
4- GainAmpMap

The expected structure for the stored constants is: in_folder/{constant_name}_{karabo_da}.h5

The expected data path for the constant array inside the h5file is: ['constant_name']

There is a change as well for the get_report(__) function in cal_tools to have the ability in injecting a report path metadata even if there is no report (i.e. no_report/<injection-date>).

How Has This Been Tested?
