25853e23 - Allow the `if_not_else` Clippy lint

Allow the `if_not_else` Clippy lint Specifically, the [`if_not_else`] lint will sometimes flag code to change the order of `if` and `else` bodies if this would allow a `!` to be removed. While perhaps tasteful in some cases, there are many cases in my experience where this bows to other competing concerns that impact readability. (Such as the relative sizes of the `if` and `else` bodies, or perhaps an ordering that just makes the code flow in a more natural way.)
