Propagate DETECTOR_PROJECT_ROOT environment variable

Add additional method to Rich MC Optical Photon helper

See merge request !3174

Add additional method to Rich MC Optical Photon helper to find photons associated to given RICH hits and MCParticles

make code compatible with gaudi/Gaudi!1249

See merge request !3217

With the new CMake configuration it is necessary to explicitly
define what goes into the runtime environment, so
`DETECTOR_PROJECT_ROOT` is added.
In addition, DD4hep is added to LD_LIBRARY_PATH to allow using a local build.

This reverts merge request !3112

add support for TH3 reading from conditions DB

Created an LHCb specific version of Functional base classes

See merge request !3187

Take advantage of namespace nesting

Drop usage of GaudiAlgorithm in favor of Gaudi::Algorithm

See merge request !3181

Tweak track_v3:

See merge request !3185

Change HltPackedDataWriter compression method

See merge request !3191

Namely, all easy case are done (the ones where FixTESPath<Gaudi::Algorithm was already the base class)
And on top the whole DAQ/DAQUtils package has been ported to them and thus moved to Gaudi::Algorithm

The idea is to be able to customize them for LHCb if needed.
The first customization leading to the creation of them is changing the
default underlying Algorithm to Gaudi::Algorithm rather than
GaudiAlgorithm

* rename `to_soa_track_type` to `to_v3_track_type`
* avoid double checking: do not check in forwarding functions what the target function will also check

Implement `get_pointer(std::optional)`

See merge request !3193

Minor fix to STDOPTS definition

See merge request !3169

equivalent of get_pointer( boost::optional ) for std::optional
( see https://www.boost.org/doc/libs/1_77_0/libs/optional/doc/html/boost_optional/reference/header__boost_optional_optional_hpp_/detailed_semantics___free_functions.html#reference_free_get_pointer )
returns a pointer to the payload of the `std::optional` if it is
engaged, or nullptr in case it is not.
