[TF3] Add efficiency, time resolution and ToA maps from ccdb

This pull request introduces improvements to the IOTOF digitizer simulation and a new macro to test the time resolution

Improvements in the digitization

• Added support in DPLDigitizerParam for specifying optional efficiency, resolution, and time of arrival map paths, which can be loaded from CCDB or various file sources

• Updated Digitizer to load these maps using a new loadMap method, supporting both CCDB and ROOT file sources, and to prepare a scaled resolution map for position-dependent time resolution

• The time smearing logic in Digitizer::smearTime now uses the loaded resolution and time of arrival maps to apply position-dependent Gaussian smearing

• NOTE: the resolution map determines the relative in-pixel resolution, while the nominal value is set by an independent parameter of the DPLDigitizerParam class

• Refactored map loading logic into a generic loadMap method and added prepareScaledResolutionMap for normalization, improving code maintainability and extensibility.

• Fixed a run-time inconsistency in the output size within IOTOFDigitizerSpec.cxx

Testing

• Added a new test macro CheckTimeResolutionIOTOF.C to the CMake configuration, ensuring that time resolution features can be tested and validated

Efficiency, time resolution and time of arrival maps can be found in the ccdb at these paths

• ccdb://Users/g/glucia/tmp/ALICE3/IOTOF/pixelEfficiency
• ccdb://Users/g/glucia/tmp/ALICE3/IOTOF/pixelResolution
• ccdb://Users/g/glucia/tmp/ALICE3/IOTOF/pixelTimeOfArrival

I will upload some examples of the mean and rms of the time resolution when the maps are used in the digitization
