DeprecationWarning

[nicklasfrahm]

Hello,

currently, when running this package in node v10.15.3 I get the following error:
(node:806) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

I will submit a PR with a fix. What is the oldest node version that should be supported? v6 or v8?

@usefulthink I really don't want to put any pressure, but is there a chance to release this change soon? If I am told, what I have to update (package.json, etc.), I can also submit a PR with that, so that you only have to create a release in GitHub.
