Add nuance code for supernova neutrinos

[AndyChappell]

Pandora uses the nuance code in some decision making e.g. does this particle come from a neutrino interaction or a cosmic ray. MARLEY sets nuance codes to 0, which breaks a lot of the logic in the decision making. This update adds an override to Pandora's internal nuance code override for supernova origin particles (code==4000).
