Add warning to set zmin and zmax for ion-acc example (#3323)
* Add warning to set zmin and zmax for ions
and also change the ion acceleration example to set these
parameters so that users are aware that memory overflow could
happen for production-size examples
furthermore, correct units in comment after definition of
r0 and Lcut
Replace zmin and zmax with variables for electrons
* Reset checksum for regression test
Reset benchmark for LaserIonAcc2d test because the particle
initialization in the input changed.
