Add arguments for resolution, fps, simulated_t

README.md

 # ALICE Open Data Blender animation
 
 Run animation example:
-`blender -noaudio --background -P animate_particles.py -- -radius=0.05 -duration=1 -camera="BarrelCamera" -datafile="esd-detail.dat"`
+`blender -noaudio --background -P animate_particles.py -- -radius=0.05 -duration=1 -camera="BarrelCamera" -datafile="esd-detail.dat" -simulated_t=0.02 -fps=24 -resolution=100`
 
 
 In the example above, argument 'radius' has value 0.05, 'duration' has value 10 and so on.
