Update lifetimes of anti-deuteron, -triton and -alpha
The zero-lifetime of the anti-deuteron currently present in the ParticleTable
leads to warnings issued by the ParticleClassificator.
To avoid any other possibly related effects in the upcoming restripping campaign, the anti-deuteron lifetime is set to the same value as the deuteron one. The lifetimes of anti-triton and -alpha are modified in the same way for consistency.
