CA: introduce error distribution range for hits

Introduce distribution range for the hits.

Since in the global / mcbm tracker hits have different distribution shapes - from Gaussian-like in STS to uniform distribution in TRD-1D, the distribution range can not be calculated from the RMS anymore. Therefore, we introduce the distribution range as an additional hit parameter. By default, the range is calculated as 3.5*RMS (for a Gaussian), but it can be set to a different value in specific cases like TRD-1D.
