From 419ff8531c163200a5e7d21d4d0f7ac7ff8d25f8 Mon Sep 17 00:00:00 2001

Subject: Remove no longer used error module

This change removes the error module. This module, and the Error type it
homes, are no longer used by the application, as everything has been
transitioned over to using anyhow's Error type.
