Changed version to reflect that it is a patch

Instead of changing to version 3.2.0, changed version to 3.1.1 because it is a patch to fix an error with writer IDs that contain letters in addtion to numbers.

Made a note in cran-comments.md that this version is a patch following instructions in https://r-pkgs.org/release.html#failure-modes
