Update Oxygen Cross sections

[sgriswol]

Updated oxygen cross sections are available, see SNEWS/sntool.

Should we implement this manually or pull in sntools for cross-section calculations?

Reviving this issue.

For convenience, the above comments refer to the interaction channels implemented here: https://github.com/SNEWS2/sntools/tree/main/src/sntools/interaction_channels

This includes an updated formulation of CC neutrino interactions with O16 based upon the work of Kolbe et al., 2002 (the same source ASTERIA uses).
