Add macro to print/dump alignment matrices in human readable text form

The tool allow to compare the content of the standard alignment root files, and can be run in any folder after loading the Cbmroot environment (so you can copy it somewhere else if you find it easier) Probably of interest to @a.bercuci @a.toia @n.herrmann @sturm

Usage:

root -l -b -q 'print_alignment.C(<setup tag>)'

Example:

root -l -b -q 'print_alignment.C("mcbm_beam_2022_05_23_nickel")'

Processing print_alignment.C("mcbm_beam_2022_05_23_nickel")...
