Hemera-snappy package

This is modified fork of hemera-snappy.

This is a plugin to use Google Snappy with Hemera.

Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression.

#### Example

``js
'use strict';

const Hemera = require('nats-hemera');
// Use NATS driver >= 0.7.2
const nats = require('nats').connect({
// otherwise NATS will interpret all data as LATIN1 (binary encoding)
preserveBuffers: true
});
const HemeraSnappy = require('@barbastudio/hemera-snappy');

const hemera = new Hemera(nats, {
logLevel: 'info'
});

hemera.use(HemeraSnappy);

hemera.ready(() => {
hemera.add({
topic: 'math',
cmd: 'add'
}, (req, cb) => {

cb(null, req.a + req.b)
});

hemera.act({
topic: 'math',
cmd: 'add',
a: 1,
b: 20
}, function (err, resp) {

this.log.info('Result', resp)
});
});
