* Add `--dump-setup` to dump unpacker setups to file.
* Add TRD and TRD2D setup files converted to YAML
* Enable TRD and TRD2D Unpacker in cbmreco
* Make TRD and TRD2D Unpacker parallel

- Small refactoring
- Add support for std::map
- Add some unittest coverage
- Add CBM_FORMAT to specify how structs should formatted in yaml

* Use `fles::InputArchive` / `fles::OutputArchive` to read / write archives
* Reuse `fles::ArchiveDescriptor` as archive header
* Removed `--split-output-per-ts` flag
* Update `RecoResultsDescriptor` to include timeslice-index and start time
* Added `--dump-archive` flag to quickly inspect written archives for basic debugging
* Removed ability to add wildcards in output filename e.g. for hostname (this should be handled by slurm-startscript)

- Rename file to Definitions.h
- Replace Detectors-enum with fles::SubsystemIdentifier

This is a workaround for a bug in older cling versions.
