To write image pickles use -p, otherwise the program writes CSPAD CBFs.
Writing CBFs requires the geometry to be already deployed.

Examples:
cxi.mpi_average -c cxi49812/average.cfg -x cxi49812 -a CxiDs1.0:Cspad.0 -r 25 -d 571

Use one process on the current node to process all the events from run 25 of
experiment cxi49812, using a detz_offset of 571.

mpirun -n 16 cxi.mpi_average -c cxi49812/average.cfg -x cxi49812 -a CxiDs1.0:Cspad.0 -r 25 -d 571

As above, using 16 cores on the current node.

To write image pickles use -p, otherwise the program writes CSPAD CBFs.

Use one process on the current node to process all the events from run 25 of
