Read_gen does not read gen files properly

Read_gen does not read gen files properly

maybe rely on PQAnylsis?

It is better to reuse the existing routines and not write a new gen file reader. Especially at the moment, there is no need for gen files. Should the read_gen be removed from the ThermoScreening?

I would add PQAnalysis as dependency or rely on ase to read in gen or xyz files
