/**
Merge and normalize adjacent or overlapping integer ranges.

The function takes an array of [closed integer ranges](https://simple.wikipedia.org/wiki/Interval_(mathematics)#Closed_Intervals).

Normalizes reversed ranges by converting them from `[3, 1]` to `[1, 3]` and also supports negative numbers.

@example
```
import simplifyRanges from 'simplify-ranges';

const ranges = [[1, 2], [3, 4], [2, 3]];

console.log(simplifyRanges(ranges));
//=> [[1, 4]]
```
