fix: to_additive translates pow to nsmul (#1502)
- I tried translating it to
smul
in #715, but that was a bad decision
- It is possible that some lemmas that want to be called
smul
now use nsmul
. This doesn't raise an error unless they are aligned or explicitly used elsewhere.
- Rename some lemmas from
smul
to nsmul
.
