CA: New MC module and external output QA-task (2.0)

• New (experimental) MC-module for CA tracking (CbmCaMCModule class), initializes MC points and tracks, matches them with hits and reconstructed tracks
• New time-slice reader (cbm::ca::TimeSliceReader class), fills external CA data structures from reconstruction output trees
• [WIP] External QA task introduction for CA tracking (cbm::ca::OutputQa class)
• Minor changes (CbmQaTask updates) and bugfixes (station indexes fix in matching TOF points for tracking)
• Track category and track fit category sub-QA classes, which handle predefined set of histograms for a selected track category (for example, primary pi-)
