Conflicting error message - PB fusion

[PhysicsDan]

Hi - great work implementing nuclear fusion!

Just to bring to your attention - this error message has a small typo in it.

When I set particle.species_type to alpha (or helium4) I get the error

0::Assertion `product_species.AmIA<PhysicalSpecies::helium>()' failed, file "src/warpx/Source/Particles/Collision/BinaryCollision/BinaryCollisionUtils.cpp", line 93, Msg: 
### ERROR   : ERROR: Product species of proton-boron fusion must be of type
#            alpha

While the code will start running when I set the species_type to helium (this matches the test inputs in this repo too).

Thanks,
Dan

Thanks for raising this issue!
This is now corrected in #4480
