PARTIALLY RESOLVED: Parameters of TPC detector should be taken from one place in the code

EDIT 2022-05-18: MpdTpcSectorGeo.h file contains the geometry parameters. All interfaces and their new implementations will take geometry from there.
Old implementations are developer's responsibility.
Closing this as partially resolved.

Currently, the geometry of detector is loaded in macro/mpd/geometry_stage1.C

but

for example the clustering algorithm MpdTpcCLusterFinderMlem.h has hardcoded static const variables describing the detector.

All geometry parameters of the detector should be initialized before the FairRun (appears to be true), but then these parameters should be taken from that initialization during the various FairTasks in the run (this is not true).

This is very important.
