Deprecated function - hex

[rahulsps]

Using node version 8.9.4 Using npm version 5.7.1

Problem: In file /@steemit/rpc-auth/lib/index.js at line 58: exports.K = Buffer.from('3b3b081e46ea808d5a96b08c4bc5003f5e15767090f344faab531ec57565136b', 'hex');

This gives the following error: TypeError: hex is not a function

Solution:

1. npm install buffer
2. include this node module in the file /@steemit/rpc-auth/lib/index.js in very beginning like below: var Buffer = require('buffer/').Buffer
