Top level middleware for catching and displaying errors (assumes using error classes from @salsita/errors).

Expects logging function as parameter.

Example:

``js
const winston = require("winston");
const Router = require("koa-router");
const errorMiddleware = require("@salsita/koa-error-middleware");

const formatUserMessage = err =>
process.env.NODE_ENV === "production" ? "Ooops something went wrong" : err.message;

const router = new Router();
router.use(errorMiddleware(winston.log, formatUserMessage));
``
