A CA iteration (L1CAIteration class) represents a set of parameters, dependent from the particular track finder
running step. Previously, default iterations were initialized in the CbmL1::Init function with hard-coded values.
Now, the default iteration list is provided in the in the configuration file. At the moment there are three
main configuration files:
   ${VMCWORKDIR}/macro/L1/configs/ca_params_sts.yaml    -- L1Algo::TrackingMode::kSts
   ${VMCWORKDIR}/macro/L1/configs/ca_params_mcbm.yaml   -- L1Algo::TrackingMode::kMcbm
   ${VMCWORKDIR}/macro/L1/configs/ca_params_global.yaml -- L1Algo::TrackingMode::kGlobal

L1: explicit implementation of copy and move constructors and assignment operators were replaced with default for L1Parameters and L1CAIteration classes

L1: replaced preprocessor macros DO_NOT_SELECT_TRIPLETS, TRACKS_FROM_TRIPLETS, TRACKS_FROM_TRIPLETS_ITERATION, EXTEND_TRACKS with flags in L1CAIteration

L1: Added boost serializers for L1Parameters objects and their components; implemented an interface for parameters and input data RW

L1: add consistency checkers for L1Parameters, L1Station, L1UMeasurementInfo, L1XYMeasurementInfo, L1MaterialInfo, L1Material, L1FieldSlice, L1FieldRegion, L1FieldValue classes

L1Algo: constexpr constants moved from L1Parameters class to the L1Constants namespace (L1Constants.h)
