Yes, sorry for that, the typo is also present in code. I mindlessly decided
both words meant the same and went with it...

So, for the record, s/arsan/argon/ should be applied on all patches, binding is
fine in that regards. On the other hand, the old arsan/rpivid ASB is referenced
as 'asb' in code, and as 'arsan' in the bindings, I'll rename both to 'rpivid'
in v2.

Actually, if all this is too confusing, let me know and I'll send a v2 right
