dual readout Detectors added to FCCDetectors

[atolosadelgado]

Hi,

This branch merged the dual readout Detectors sub-directory into the FCCDetectors repo.

I followed these steps:

1. Filter the commits in the initial dual-readout repo using git filter, as explained here
2. I pushed the filtered commits to an intermediate remote repo
3. I merged the intermediate repo into FCCDetectors as explained here. Please, let me know if this is done in the proper way
4. I included the new subdirectories in the CMakeLists as new commit

I checked that the proyect can be built using this flags,
cmake ../FCCDetectors/ -DCMAKE_INSTALL_PREFIX=$PWD/../install -DEXECUTABLE_OUTPUT_PATH=$PWD/../install

If the last flag EXECUTABLE_OUTPUT_PATH is not provided, there is an issue with the DD4hep macro called in line 31 of this file, and the project can not be configured.
line 31: dd4hep_configure_scripts( ddDRcalo DEFAULT_SETUP WITH_TESTS )

Can this be an issue?

Thanks you for your time.

As discussed, please add a test and resolve the conflicts. The dd4hep_configure_scripts call can be removed.

I added a test to scan the X0 parameter using the materialScan command from DD4hep. The bash script takes 3 arguments, the compact file and two arguments that are used for defining the test:
-axis: along the material scan is done. At the moment, 'x' or 'z'
-material check ('air', or 'noair'): if 'air' condition is passed as argument, the X0 is checked accordingly: the test will fail if X0 is larger than X0 of air. The opposite is true when 'noair' is passed.
