map file doesn't match \r\n

i suspect helm charts created with macosx have an issue where my ingress was not getting matched because the file had \r\n instead of \n like in the map file.
my workaround was to use the following mapping

- deprecatedAPI: "apiVersion: networking.k8s.io/v1beta1\r\nkind: Ingress\r\n"
newAPI: "apiVersion: networking.k8s.io/v1\nkind: Ingress\n"

but i'm sure a quick string replace would be a better solution for this.
