Add map_err_ignore lint In a large code base a lot of times errors are ignored by using something like: ```rust foo.map_err(|_| Some::Enum)?; ``` This drops the original error in favor of a enum that will not have the original error's context. This lint helps catch throwing away the original error in favor of an enum without its context. --- *Please keep the line below* changelog: Added map_err_ignore lint
