### isSafePositiveInteger
Ensure positive integer less than `Number.MAX_SAFE_INTEGER`
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER
```js
var isSafePositiveInteger = require('is-positive-integer').isSafePositiveInteger
// max safe integer doesn't exist in older engines
var MAX_SAFE_INTEGER = Number.MAX_SAFE_INTEGER || 9007199254740991

isSafePositiveInteger(MAX_SAFE_INTEGER) // true
isSafePositiveInteger(MAX_SAFE_INTEGER + 1) // false
isSafePositiveInteger(Number.MAX_VALUE) // false
// ...
```
