Introduce an all new unpacking scheme and implement the TRD as example #2148

This MR contains:

• run_unpack_tsa.C/run_unpack_online.C steering macros

• CbmSourceTsArchive implementation of a FairSource for the unpacking scheme

• CbmRecoUnpack distributor of Timeslice components to the subsystem algorithms

• CbmRecoUnpackConfig.tmpl template class for algorithm configuration during run initialisation

• Subsystems can/should derive a explicit config from this template and add that to CbmRecoUnpack

• CbmRecoUnpackAlgo.tmpl template class for the algorithms themselves

• Subsystems can/should derive explicit implementations for the algorithms from this class

• CbmTrdUnpackConfig implementation of CbmRecoUnpackConfig for the TRD

• CbmTrdUnpackAlgoBaseR

• Implementation of a TRD-1D (spadic based) unpacking algorithm base clase

• CbmTrdUnpackAlgoR(AlgoLegacy2020R) explicit unpackers for given raw data types from the spadic

• CbmTrdRawToDigi... implementation of feature extraction (time and energy reconstruction) from ADC samples of the Spadic
