Improve usage of FLES IPC TimesliceAutoSource interface
- Make usage of the vector interface (later to become the only one)
- Add vector constructor to CbmSourceTsArchive
- Make vector input default in run_unpack macro
- Restore possibility of semicolon separated list of streams for TSA input
- Call string constructor of FLES IPC TimesliceAutoSource if vector of size 1
- Add alternative call with single string to run_unpack_macro to keep legacy interface available
