Copy files with emitter (even from and to `zip archives`). It will emit event on every percent of copied chunk of data.
Good for making progress bars.

### Install

```
npm i copymitter
```

### How to use?

```js
import {copymitter} from 'copymitter';

const cwd = process.cwd();
const from = `${cwd}/pipe-io`;
const to = `${cwd}/example`;
const abortOnError = false;

const cp = copymitter(from, to, ['LICENSE', 'README.md', 'package.json']);

cp.on('file', (from, to) => {
    console.log(`${from} -> ${to}`);
});

cp.on('directory', (from, to) => {
    console.log(`${from} -> ${to}`);
});

cp.on('progress', (percent) => {
    console.log(percent);
    
    if (percent >= 50) {
        cp.pause();
        cp.continue();
    }
});

cp.on('pause', () => {
    console.log('paused');
    cp.continue();
});

cp.on('error', (error) => {
    console.error(error.message);
    
    if (abortOnError) {
        cp.abort();
        return;
    }
    
    cp.continue();
});

cp.on('abort', () => {
    console.log('Copying aborted');
});

cp.on('end', ({errors}) => {
    console.log('Copying ended up');
});

cp.pause();
```
