Overflow when encoding a big integer

[tdzl2003]

When I encode a big integer(bigger than 2^31), it overflow and got a negative value in Node.js

This is because parseInt doesn't limit integer value in 32bit:

> parseInt(12345678901234)
12345678901234

Change the line:

var intVal = parseInt(val);

into:

var intVal = val | 0;

will solve this problem.

I can confirm that. That's a very unfortunate bug because it makes impossible to serialize timestamps thus making this package unusable for many programmers.

Simple reproducing case:

const PSON = require('pson')
const pson = new PSON.Pair()

const testData = {
	ts: Date.now()
}

const buff = pson.encode(testData)
const testDecode = pson.decode(buff)

console.log(testData.ts, testDecode.ts)
// outputs 1531344982502 -1958342170

@nonphp You can try my incoming pr #10

Still not working

const PSON = require('pson') // 2.0.0
const pson = new PSON.ProgressivePair(['ts'])

const testData = { ts: 15313449825 }
const buff = pson.encode(testData)
const testDecode = pson.decode(buff)

console.log(testData.ts === testDecode.ts, testData.ts, testDecode.ts)
// outputs false, 15313449825 -1866419359

@Josema You can try my fork or modify that line manually and use patch-package to keep the changed line., this pr is still not merged.
