We already have the results for the inverse of formal multilinear series, so this PR is mostly just extending our API. However, this showed that our API is suboptimal (notably with respect to the choice of constant coefficients in inverses of formal multilinear series), so we also tweak the definitions of `FormalMultilinearSeries.id` and `FormalMultilinearSeries.leftInv/rightInv` to make them more usable.
