Changes: * changed the default maximal number of records read from CORSIKA files to 0 * corrected the nuclear mass formula in `GSeaCORSIKAFileFlux::CorsikaRestMass` to include nuclei with odd mass numbers, e.g. Helium-3 (from v7.1.2): * added manual control of the maximal number of records read from CORSIKA files * suppressed the unnecessary printout at the end of processing of a CORSIKA file (from 7.1.1) * added the CORSIKA-specific info about the penetration depth in g/cm^2 * minor fixes (from 7.1.0) * fixed muon propagation, so that now muons should not end up deeper than 5m inside the can. * propagation step length and first (bigger) step length can now be defined by the user with `--propagation-step` and `--approach-dist` (although it is recommended to stick to the optimized default values) * readout of the MUPROD option from CORSIKA was corrected * a problem with wrong use of UnstableParticleDecayer was solved
