add support for parsing vectors of enums in TrackEnums
Add support for eg. Gaudi::Property< std::vector<LHCb::Event::Enum::Track::Type> >
which requires adding StatusCode parse( std::vector< LHCb::Event::Enum::Track::Type>&, const std::string& )
for the various enums defined in TrackEnums. To be used in various track monitors for alignment.
