L1 bugfix: Changed iSta (local geometry station index) to iStaGlob (global active station index) in addressing to a L1Station object for TOF MC points selection

CbmTofInteraction class is introduced to address the problem of multiple MC points for one interaction.

L1: U and V coordinates and uncertainties conversion methods were refactored and moved from L1Algo to L1Station

L1Algo: constexpr constants moved from L1Parameters class to the L1Constants namespace (L1Constants.h)
