[DEP0005] DeprecationWarning: Buffer() is deprecated

[dex4er]

Hi. With Node v10.1.0:

$ NODE_OPTIONS='--throw-deprecation' npm test

> bramqp@0.5.0 test /Users/dexter/src/js/bramqp
> vows --spec

  ♢ concurrent connections

events.js:167
      throw er; // Unhandled 'error' event
      ^

DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

This has been fixed in commit 24b57426 and pushed in version 0.6.0

In order to accommodate the newer Buffer api, many older node versions were dropped as part of this change.
