* Remove dependency on `more-asserts` In my recent adventures to do a bit of gardening on our dependencies I noticed that there's a new major version for the `more-asserts` crate. Instead of updating to this though I've opted to instead remove the dependency since I don't think we heavily lean on this crate and otherwise one-off prints are probably sufficient to avoid the need for pulling in a whole crate for this. * Remove exemption for `more-asserts`
