Disable particle table advice

I put the reasoning in the code comment as well, but in order to have it here:

The loaded particle table creates particles that have
decay widths but the actual decay process is not defined within Geant4; thus, if one
of the particles that is created happens to trigger a decay within the Geant4 world,
it will create a Segmentation fault when trying to access the uncreated decay process.
The particle table loading is helpful for the General Particle Source (GPS) since it
needs to have these extra particles defined.

I don't think my hypothesis is correct anymore so I'm closing this PR.

I still see the Seg fault that I thought was due to the particle table after disabling it, so I'm guessing it is due to something else.
