Allow building with GHC 8.8

Some other minor changes:

* This doesn't actually build with GHC 7.4/`base-4.5` due to the use
  of `LambdaCase`, so raise the lower version bounds on `base`
  accordingly.
* The `Data.Monoid` import is completely redundant, even on older
  GHCs. This patch removes it to avoid warnings.
