Bad handling of interupted file

gtot does not seem to handle properly a binary file that has been interupted (seg fault), even though the produced ROOT file is usable. Would be great if gtot could close gracefully in that case as well Thank youuuuuuuuuuuuuuuuuuuuuuuuuuuuu PS: file tested was GP80_20250421_021051_RUN156_MD_20dB-GP13-DU58-ChXorChY-Y2FLOAT-NEW-LNA-0001.dat
