6.0.0 (2018-12-15)

@bdeitte Major upgrade to the codebase to be more modern, overhaul tests, and many small tweaks. Most of this is internal to the project, but there are a few changes to note for everyone:

Now requires Node 6 or above
Update close() to handle errors better, not doubling up in error messages and not leaving uncaught errors

Everything else done here should be internal facing. Those changes include:

Use "lebab" to ES6-ify the project
Switch from jshint and eslint and make syntax updates based on this
Remove a lot of duplication in tests and many small fixups in tests
Start using Mocha 4
Stop using index.js for testing
Start using the code coverage report as part of the build
Remove the ignoring of errors on close of tests, and tear down tests in general better
Stop using "new Buffer", that is deprecated, and use Buffer.from() instead
